Subject: Re: folder internal data
Those "Folder Internal Data" pseudo-messages have nothing to do with
QPopper. They are placed in the user's mail spool file (also in any Pine
or IMAPD saved messages files) by Pine 4.x and the UW IMAPd server.
They are ignored by Pine 4.x and by IMAPd, but are treated like any other
message by other mail software.
The simplest solution, which won't break Pine or UW's IMAPd, is to use the
"--enable-uw-kludge" option when you run QPopper's configue script, then
recompile. That will make QPopper ignore the "Folder Internal Data"
messages.
Or, you can put "quell-internal-folder-msg" in a site-wide pine.conf.fixed
configuration file. That will stop Pine from creating the
pseudo-messages. Trouble is, this will break some of Pine 4.x's more
advanced features. Also, it won't stop IMAPd from creating the messages.

I think not. You won't have a port open on 110 unless you set it to
on a separate instance of the daemon. "alternate-port" means that
you've told it you *are* running it on an alternate port, so I think
it's exactly what you want in this case.
Just don't run an instance on port 110, use "alternate-port" and 995
as you've set, and I think you will have exactly what you want. If
it's still opening up something on port 110, then maybe you need to
check your inetd.conf or xinetd.conf and see if those were removed.

I probably should have done a bit more experimenting before posting to
this list. Tell you what; I'll test it out tonight when I get home and
report back to everyone tomorrow.

If you set 'alternate-port', that tells Qpopper to do a TLS/SSL
negotiation as soon as the connection opens. There is no fall-back.
If the TLS/SSL negotiation fails, the connection is closed.
(If you use 'stls', then the session can be either TLS/SSL or not.
In that case, setting 'clear-text-passwords' to 'tls' (or 'ssl')
prevents users from authenticating without TLS/SSL or APOP. If APOP
isn't enabled then it isn't an issue.)

You don't have to recompile anymore. Most compile-time options are
also available using a configuration file. See the Administrator's
Guide.
(Run-time options can be much more convenient.)

Depends on what services you'll run. From /etc/services:
25 SMTP
109 POP2
110 POP3
143 IMAP2
220 IMAP3
587 SMTP/submission
993 SIMAP
995 SPOP3
There's a bunch more for some more esoteric mail systems.

Subject: Redownloading all messages after move to qpopper
I'm hoping to move our pop server to qpopper 4.0.3, and have been
doing some testing. The one thing that worries me is that when using
Eudora, when I switch the pop server to qpopper 4.0.3 (from RedHat's
default pop server) my mail client regrabs all the mail in the spool.
Looking at network traces shows that the UIDLs are in fact different.
Each time I switch back and forth between the pop servers, Eudora
regrabs the entire spool.
I found the "update-status-headers" and "old-style-uid" options in the
config file, and thought that might fix the problem, but as far as I
can tell, changing these to false and true respectively didn't do any
good. In fact, the UIDLs in a network trace look the same as before.
Is this even a qpopper issue, or is it maybe a Eudora issue?

Hi all,
Could someone please shed some light to the situation that I have.
First of all I have installed and make and make install the files. I am
running redhat 7.1, so I had to change the xinetd instead of inet files.
When I telnet localhost 110 everything is working okay and I am able to get
retrive the emails that have been sent to my domain. But then when I do a
port prob test the tests comes back reporting that the pop3 port is in
stealth. And also I can not retrive my mails using the mail clients
(outlook, eudora). I am using postfix as my smtp and it works okay and I can
send mails.
My DNS is not on my machine and is being done at zoneedit.
Can someone please let me know what could be the problem, or what other
files need to be configured.
Thanks a lot

Subject: QPopper client connection fails on POP3
Date: Wed, 24 Oct 2001 16:05:02 -0500
I am a newbie to the Linux/Mandrake arena. I am building a firewall with
Mandrake Single Network Firewall 7.2. I am using Postfix for the MTA. I
installed QPopper 4.0.3 with little problems. I ran the tests on the port
on the firewall and it allowed me to log in and told me I had mail.
However, my workstations run Outlook Express 5.0 and Outlook 97 for mail
clients. The Server seems to timeout when the mail client sends a request
to the server. I have checked the port on the server and it seems to be
fine. I don't seem to find any discrepancies in the log file, it seems
that the client never talks to the server according to the log file. I ran
some basic network tests on the workstation and the server and they are
talking to each other. Is there something in the configuration or am I
missing something in the documentation? Help?

Looks like some problem with your certificate file. How did you create
it? I'm using a self-signed cert with no problems. The client will
complain initially that the signing authority is not recognized, but
you just have to manually add it to the client's list of trusted certs.
Eudora has a Cert Manager button in the Options dialog to do this.

What happens if you try to telnet to port 110 from one of the failing
clients?
You don't say if your firewall is part of Mandrake or a separate box.
Linux has its own firewall capability, so perhaps you're still blocked
there. Check the Linux logs. ("ls -lt /var/log | head" should tell you
which log files were just written, so do that right after a failure to
see which log files might have information about the failure.)

Sounds like you have a firewall, which is new with Red Hat 7.x. You
need to punch a hole for port 110 to the outside world. Make sure you
can do "telnet mailhost 110" from the client, not from the server.

It wouldn't, out of the box. If it appears to be, then perhaps there

It's just a fact of life. Different servers use different algorithms
for assigning unique IDs to mail messages. 'update-status-headers'
specifies if the UID, once generated, is written back into the spool,
or instead must be recalculated each time. 'old-style-uid' controls
use of newer, more compact UIds versus the old ones.
It may be possible to have a script add 'X-UIDL:' headers to the
spool containing the old server's UIDs, causing Qpopper to use them.

Subject: Re: QPopper client connection fails on POP3
Some other suggestions:
1) Can you turn the firewall off and see if your mail clients can then
collect mail?
This would confirm whether or not the firewall is the issue.
2) Although you logged on and were told you had mail, you have not said
whether you successfully retrieved any. Have you ever done this with the
firewall running?
3) Can you increase logging, as it sounds like the problem is not
currently being logged? This means both firewall and system logging btw.
4) Are you sure that TCP wrappers are not keeping the other workstations
out? (Check /etc/hosts.allow and /etc/hosts.deny for popper entries.)
Do let us know of your progress.

When a user tries to check their mail, qpopper first attempts to copy the
mailbox to a temporary area from which the user then downloads. Where that
file is depends on how you have configured qpopper, but can be
/var/spool/mail/user or /home/.user.pop for example.
The error message you have is telling you that qpopper cannot copy mail to
the temporary area due to a problem with permissions. You therefore need
to a) find out where it is trying and b) make sure that the permissions are
adequate there.
I am sure that you are also going to get comments about using a more recent
version than 2.53 as well...

Indeed, 2.53 is very old and has known vulnerabilities. The current
code base is much more robust. I strongly urge upgrading to 4.0.3
immediately.

Good suggestion.
Probably that's it; it's got the pair of ports, and because they're
under RPC, the port numbers are presumably dynamically defined. Not
having tried out DRAC, I have no idea how that's supposed to work.

That sounds likely. The listen port is of course fixed, but each
instance of Qpopper (of which there might many, simultaneously, serving
different users) is going to need its own outbound port to talk to the
DRAC daemon.
I'm not real familiar with how much control one can have over an RPC
client/server, but it might be possible to restrict what interface is
used for the sockets, so that all RPC traffic is forced through the
loopback interface. You may need to do this at the source code level. I
don't recall seeing any settings for DRAC or Qpopper to select the
interface. I just trust ipchains to block that port to the outside
world.

Subject: qpopper 4 causes CPU load to rise
Hello all
I would like to introduce myself , I am sysadmin in Zambia , and
have been using qpopper for a few years now.
Unfortunately , over the past 2 days , I seem to be having a
problem with my mail server. We are runing Slackware 7.1 ,
with sendmail 8.11.4 , procmail 3.22 and qpopper 4.0.3.
What we are seeing is that when sendmail tries to deliver
mail to all our users at once ( when we issue a blanket email
to our subscirbers ), it will deliver half of the messages , and
then give up with the message
"timeout waiting for input from local during Draining Input"
Meanwhile , qpopper sessions for the mailboxes that have
NOT received the mailing yet begin to go into a "dead" state,
and do not allow anyone to login. These sessions cannot be killed,
and they increase as each person tries to pickup mail , until the
cpu load average reported by the system causes the MTA to
begin rejecting connections ( approximately 10 mins )
When the server gets to this state , it is nearly impossible to
list the files in the mail spool directories ( it is still possible to
move around the rest of the file system ).
Has anyone come across such a strange phonomenon , is it
a DOS attack ?
I would appreciate any help offered.
Kindest regards

Don't know if it's your problem or not but the version of Sendmail you are
using needs to upgraded to at least 8.11.6
There are holes that a user can use on a Linux system via sendmail in that
version.

That is a Sendmail issue. See
http://www.sendmail.org/~ca/email/smenhanced.html a brief explanation of
the "Draining Input" syslog message. It may or may not apply to your
situation.
How many addresses are on the recipient list for these mass mailings?
What distribution mechanism do you use?
If you're using mailing list management software (Majordomo, Listproc, or
similar), this shouldn't happen. However it can easily happen if you are
using a plain alias list (in /etc/mail/aliases or your local equivalent)
to deliver to your subscribers, and if your subscriber list is fairly
large. I used to see it occasionally under a certain combination of
circumstances: When sending to a group of nested alias lists totalling
about 800 addresses *AND* cpu usage was already high *AND* there was a lot
of disk I/O occurring on the disk that contains the mail spool.
Switching my large lists to Majordomo control solved the problem. I use a
majordomo mailing list comprised of almost 9000 local addresses to send
info to my users, and I never see a "Draining Input" message resulting
from it.
Alternately, if all your users use POP clients to read their mail, why not
use QPopper's "POP Bulletin" feature instead of a mailing list? This
writes the message to the user's mailbox only when he/she makes a POP
connection, so the load is spread out over a much greater time period.

It's difficult to tell without more information, but I suspect you're
running into a disk I/O bottleneck situation. Consider this: It's common
in a traditional UNIX file system layout for logging, mailbox storage, and
Sendmail spooling to occur on the same disk (in /var/log/syslog, /var/mail
& /var/spool/mqueue, for example). If you add QPopper and use the same
disk (let's say /var/spool/poptmp) for its temp files, you've added
another potentially I/O intensive activity to the same disk.
If your setup is like that, when you send your mass mailing, your MTA
(sendmail) is probably writing it to and then reading it from
/var/spool/mqueue, and logging each action to /var/log/syslog. Your MDA
(procmail) is writing each copy of the message to /var/mail/<username>.
At the same time, for each connected POP client, QPopper is reading from
/var/mail/<username> and writing to /var/spool/poptmp/.<username>.pop.
If your subscriber list is large, that's a lot of disk I/O concentrated
into a relatively small amout of time.
Do you have a version of "top" that shows how much processor time is spent
waiting for disk I/O? If when you send one of your mass mailings the
processor idle time drops to near zero and the I/O Wait percentage goes
very high, then you've got a disk I/O bottleneck.
How you solve the disk I/O bottleneck depends on what your current disk
setup is like. If you have slow disks and a slow disk controller, then an
upgrade to faster hardware might help. Alternately, rearrange your disk
space (and mount points) so /var/spool and /var/mail (or the equivalents
on your machine) are on separate disks from the reast of /var (and if
possible, separate disk controllers). That's what I did, and it made a
tremendous difference in mail system performance in general and QPopper
performance specifically.
Or, as mentioned above, switch to QPopper's "POP Bulletin" method to
spread out the load. Unfortunately that isn't practical on my system
because it doesn't work for IMAP users, or for those who use Pine, Elm,
etc in the UNIX shell.

Subject: Qpopper makes me cry
Okay, I posted a few days ago because I wanted to know how to get qpopper
4.0.3 to only allow alternate-port SSL connections. I guess I spoke too
soon, because I can't get qpopper to do alternate-port SSL at *all*.
Here's my sad tale:
I configured it with --enable-standalone and --with-openssl. It compiled
and installed fine. I created and signed the certs. When I run it straight
with no config file, it works fine, but of course only standard POP3 on
port 110. When I run it with this config file:
set tls-support=stls
set tls-server-cert-file=/usr/local/etc/certs/cert.pem
It accepts standard and SSL connections on port 110, and I can get my mail
fine with the latest Eudora set to force stls.
So far, so good. Here's where it gets weird. When I change my config file
to this:
set tls-support=alternate-port
set tls-server-cert-file=/usr/local/etc/certs/cert.pem
It still only opens port 110. Port 995 is closed. Now when I set Eudora to
force stls, it times out. When I set it to force alternate-port, it gets a
refused connection. When I set it to unencrypted POP3, it times out. A
manual telnet to port 110 looks like this:
NEW-JINX: /usr/local/etc# telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.unknown.nu.
Escape character is '^]'.
USER sluggo
Connection closed by foreign host.
So I'm stumped. This seems pretty straightforward, but I must be missing
something. Anyone know what I've forgotten?

Thats what have done:
I wrote this configure scripts:
----> tssl_popper.conf:
# QPopper-configfile
# for SSL Connections at port 110
#
set tracefile = /var/log/popper.log
set tls-support = stls
set config-file = /etc/QPopper/common_popper.conf
<-----------------
-----> alt_popper.conf:
# QPopper-configfile

set tls-support = alternate-port
set config-file = /etc/QPopper/common_popper.conf
<-----------------

set log-login = true
set timing = true
set timeout = 600
# the cert and the server key
set tls-server-cert-file = <somewhere>
set tls-private-key-file = <somewhere>
<-------------------
Compiled popper with
./configure --enable-log-login --enable-standalone --with-openssl=.../openssl-0.9.6b --with-pam --enable-timing --disable-update-abort
(Ok, it's a little bit ultra.)
The daemons started via:
/usr/sbin/popper -f /etc/QPopper/tssl_popper.conf
/usr/sbin/popper 212.201.18.80:995 -f /etc/QPopper/alt_popper.conf
I can have alternate connections on port 995 and normal SSL connections on port 110.
If you set the clear_text_password option right, it should be possible to
only have SSL only connections (on both ports, or on one port, do what you like)
I don't test it yet.
But the above settings working for me (on a heavy stress system, perfectly).

Aha! You're set up a bit more elaborately than I need to be, but you gave

You have to *specify* port 995 on the command line. That did the trick
Thanks so much!
(Note to Qualcomm folks: this is dumb. Maybe in a future release
specifying alternate-port in the config will automatically open the
alternate port? At least drop a note in the manual explaining this is
necessary when not running from inetd.)
So I'm all set, and it works just about exactly how I want it to. (Eudora
and Outlook Express have no problems, Mozilla can't hack it but I think
that's a Mozilla bug). Now, I just have three minor questions and I'll
quit bugging y'all:
1) How do I tell it to write a PID file to a particular directory? Or
write one anywhere, for that matter?
2) Is there a way to specify just the port on the command line, not the IP
address? This isn't a big deal, just curious.
3) What SSL-aware POP3 clients are out there? Right now I have Eudora 5,
Outlook Express 5, and Mozilla as of 0.9.4. Anyone know of any others?

Hi all,
I have several pop3 servers Qpopper 4.0.3 and serveral smtp servers. How
to make all pop3 servers send drac records to all smtp servers when
users logon? It seems the "drac-host" parameters to qpopper supports
only 1 drac-host.
If not, I may have to make a "master drac" server configuration, where
one smtp server gets all the drac first-hand, others get updates from
the master. But how can I synchronise the master and the slaves? Use
periodic rsync? NFS? Please recommend.
Thanks.
Ken

No. At least not the 4.x or 6.0 releases. They had SSL for IMAP, but not
for POP. Never understood that. Also, their SMTP TLS support is terrible
(doesn't have an option to save password). We've given up on Netscape and
been switching users over to Eudora.

Because you're only binding to port 110. Setting 'tls-support' to
'alternate-port' tells Qpopper to insist on an SSL/TLS negotiation as
soon as the client connection opens. It does not tell Qpopper to
listen on a different port. You tell Qpopper which port to use (in
standalone mode) on the command line.

Because the STLS command won't work in 'alternate-port' mode.
'Alternate-port' mode is really an ugly kluge for clients that aren't
smart enough to use STLS.
>When I set it to force alternate-port, it gets a
>refused connection.
It would work if you also told it use port 110 for alternate-port, or
if you told Qpopper to listen on port 995.
>When I set it to unencrypted POP3, it times out.
Because Qpopper is in 'alternate-port' mode and is insisting on an
SSL/TLS negotiation right off the bat.

Just as an aside, I wanted to point out that if you're using a config
file anyway, you don't need to set options such as '-enable-timing'
and '--disable-update-abort ' when running ./configure, as you can do
it in the config file, which is more flexible (it allows you to set
it different ways without recompiling).
It certainly works either way, and there's no harm in using
compile-time options (or even both, as you're doing for some of them).

Just omit the IP address. For example, ":995".

I hope this gets added to a future release. It's not the end of the world
that it doesn't have it, but rc.d-style scripts generally depend on being
able to read a PID file somewhere for the "stop" and "restart" options.

Subject: pop and Solaris 8
Hi,
We want to run pop on a Solaris 8 system.
And we want to copy mail from an older, pop/Solaris 6 system to this
newer system.
We have some questions related to this...
Do you know whether qpopper (4.x I guess?)
runs on Solaris 8?
Is pop included with Solaris 8?
If not, where is the best place to get pop for solaris 8?
Sun's shareware/freeware site?
Or Qualcomm?
Is the pop program at Sun' shareware site the same as the one at
Qualcomm's site?
We currently run an older version of qpopper on a Solaris 6 mail server.
And we would like to copy that mail to the new Solaris 8 server
periodically. The Solaris 8 mail server act as a warm backup for now.
Are there any potential compatibility problems we might run into if the
mail spool files are copied from the older version system to the newer,
Solaris 8/latest pop, based system?
Thanks,
Jon

The DRAC daemon is intended to run on the same host as the SMTP daemon
(eg. sendmail) and accept registrations from many servers running POP3
services.
It may not be necessary to run multiple DRAC daemons, if you can figure
out how to get your SMTP daemon (which one?) to consult a map on a
different server. Then you just need to configure all your SMTP servers
to connect to the DRAC server to read its drac.db.

That's way beyond my knowledge. (I just admin a server for about 100
people, and haven't needed cluster-level horsepower.) I'd recommend
asking on the comp.mail.sendmail newsgroup. The question to ask is how
to get sendmail to consult a "map" on another server. The fact that
DRAC created the map is incidental. It may be relevant that the map is
highly dynamic, since otherwise it would be trivial to replicate it
with normal file replication tools like rsync.

Most likely firewall, either netfilter, ipchains, or tcp_wrappers
(/etc/hosts.{allow,deny}). Immediately after connecting, type "ls -lt
/var/log | head -20" and watch what files appear at the top of the list
(ie. those that just changed). Then run tail on those files to look for
reports of firewall violations.

Perhaps they have an option set in their mail clients to leave messages on
server. They should disable this option if so.
