You don't have to put the private key in its own file if you don't
want to. It defaults to the cert file.

Even easier, you can simply use ":995" (maybe even just "995").

To make life a bit easier, use the three-file method as specified in
the Administrator's Guide. The file for the port 110 instance has
only two lines; one telling Qpopper to support STLS and the other
saying to read the third config file. The file for the port 995
instance also has only two lines; one telling Qpopper to support
alternate-port TLS and the other saying to read the third config
file. The third config file has everything else you want to set,
such as the cert file and any other options.

Why forever? Worst case should be that Qpopper never gets an error
whilst sending packets, so it sends all for the message, then waits
for input. While waiting for input it times out and cleans up.

You forget TCP Window: if the receiver doesn't ACK datagrams, your TCP
stack will block you until TCP sending buffer empties. If the client is
down, the buffer won't be ever emptied, since the receiver is not
ACK'ing data and the server TCP stack keeps trying forever while qpopper
is simple blocked in the "write" system call.
In fact, TCP stack will giveup finally, but my Solaris boxes TCP/IP
stacks keep trying for an entire week before give up. The qpopper will
notice the failure.
Tunning kernel parameters is not a sensible option :-).
You can checkout this problem doing the following:
a) Server and client in different machines, on the same local Ethernet
LAN
b) Set the client Ethernet address statically on the ARP server table.
This way, server will not timeout the link early by a ARP timeout
refresh.
c) Start downloading a long message. The transmission must last several
seconds.
d) In the middle of the transmission, unplug the client's ethernet
cable.
e) Try commands like "truss" (Solaris) or "ptrace" (Linux) on the
server's qpopper and see the process blocked in a "write" o similar
system call.
f) Count hours, days or weeks (accoring to your system version and
tunning:-) before server TCP/IP stack gives up and notifies qpopper
about the problem.
A simple solution would be doing an "alarm()" just before the "write"
calls. The problem would be to choose a sensible timeout, since the link
can be slow but not "black-holed".
"getsockopt" gives you the TCP/IP buffer size. If you tolerate clients
as slow as 1byte/second (fairly slow :-) and kernel TCP/IP buffer size
is reported 8192 bytes, for example, you could fix a timeout of 8192
seconds (more that 2 hours). Or you could use a fixed timeouts like "30
minutes".
This timeout is not for message sent, but per "write" syscall.

Hey Guys,
I know this is a qpopper list, but sendmail works "seamlessly" with qpopper
I thought I would give a sendmail problem a try. (I'm really just

And indeed it cannot. For starters. you have a reverse DNS lookup problem;
aharris.eboundhost.com resolves to 65.209.155.218, but the reverse DNS
lookup of 65.209.155.218 fails: "can't find 65.209.155.218: Non-existent
domain". Then, when you do a "nslookup -query=mx aharris.eboundhost.com", it
turns out you have no mail exchanger defined either: "*** No mail exchanger
(MX) records available for aharris.eboundhost.com". Your ANAME (not the
CNAME) does have a mail exchanger defined, though: "eboundhost.com
preference = 10, mail exchanger = mail.eboundhost.com".
Back to the drawing board. :) And you're right: this really is not a
sendmail list; sendmail only speaks SMTP, not POP.

There is a problem, nevertheless: efficiency. If you do a "signal" and
two "alarm" per "write", your CPU usage will goes up. We should take
some experiments here to measure real impact.
With a 512 "chunk" write buffer, for example, a megabyte email will
have, at least, 2048 "write" calls.

There's loads of sendmail support on the comp.mail.sendmail newsgroup.
You should start by searching that group using Google Groups
(http://groups.google.com/) using the advanced search feature to limit
the query to the sendmail group.

That was my suspicion, before doing any research. Thanks for doing the
legwork.

How about wrapping the entire transaction, not the individual writes?
That would mean only one alarm and signal call for the entire megabyte.

That happens. I made some changes which I think are in 4.04 which help
ensure that's the case. I run my server with SO_KEEPALIVE added as well,
which may help in this regard.

Subject: Clear text passwords with Qpopper 4.0.3?
Hi
I just subscribed to the list, so excuse me if this is a common inquiry
(couldn't find anything in the archive):
I have installed and configured Qpopper 4.0.3 with SSL support, almost
everything works fine, I'm able to connect to the server with STARTTTLS
checking and sending mail. But since the whole point with SSL is to keep
passwords and other "mail communication" encrypted I wanted to make sure
only SSL sessions was used towards the server. According to the
documentation this is done using one of the "clear text handling options",
either '-p 4' as a command line option, or in the configuration file with
'set clear-text-password = tsl'.
I have tried both. With the command line option I immediately get
"connection closed by foreign host". And with the configure file variant
I'm unable to connect at all, with or without SSL.
Obviously this isn't the way one wants it to function …
I'm running on a Linux box with 2.4.7-10 kernel, and I have of course
configured and complied popper with '--with-openssl'. In my configuration
file I have:
set tls-support = stls
set tls-server-cert-file = /etc/mail/certs/cert.pem
And I start popper from xinetd with the the following command line options:
qoppper -p 4 -t /tmp/pop.log -s -f /etc/mail/qpopper.config
As you can see I have a debug log but I don't get anything useful from it,
it only shows that the configuration file is read, it doesn't show the
rejection with results in the "connection closed by foreign host" on the
client side.
Have anybody got this to work? And if so could you give me any pointers?
Best regards Stefan Brunosson

SO_KEEPALIVE will help, for sure. But keep in mind:
a) Tipical keepalive's are sent every two hours... large periods for
detections.
b) Keepalive doesn't help you if the destination is a true black hole
and drop every packet.

Make it adaptive: Time the first chunk and use a derived timeout for all
the remaining chunks.

These link problems are coming from the crypto library on your system,
which has undefined references. Since all of them seem to refer to
dynamic loader functions (dl prefix) my guess is that you'd need to add
"-ldl" to the list of libraries used in the Makefile. I'm not much of
a Linux user though, so maybe you want to get a second opinion on this.

Bad news: They don't support APOP. (What? Security from a Microsoft
product?!)
Instead, you could set up Qpopper over SSL. I believe Lookout Express
supports that. Not sure about regular Outlook.

Qpopper is not responsible for putting messages into the mailbox. It's
responsible for getting them out. You need to look at your delivery
agent (often procmail) and transfer agent (often sendmail).

Not that it's any help, but for what it's worth our Outlook users report
the same problem fairly often. It doesn't seem to affect our Outlook
Express, Eudora, Netscape, etc. users. I'm inclined to think it's an
Outlook issue, but we have so few Outlook users I haven't taken the time
to pursue it.

What happens when you telnet to port 110 from one of the problem
clients? This will tell you if the problem is with Outlook or with the
network connection from that client.

popauth is not needed to use qpopper. popauth just creates APOP
passwords. If you use plaintext passwords, then popauth can be ignored.
qpopper uses the native user database (eg. /etc/passwd) and for users
not entered by popauth, the native password system (eg. /etc/passwd,
/etc/shadow, PAM).

I've been seeing several people today reporting simuliar pop3 timeout issues
with outlook 2000 and outlook express on the RedHat support list.
So far, the people I've talked with are running some kind of pop3 service,
like qpopper, via a service like inetd. It also appears to be happening for
the ipop3d.
The timeout problem started happening at my company after a user downloaded
a new update to the McAffee virus scanner.
My theory is the virus update contained some kind of shared COM component
that outlook uses to retrieve pop3.
If anybody figures this thing out, please post a message.
Thanks!!!

Some virus scanners install a proxy POP3 server on the local
workstation. The email client is then set to consult this proxy, and the
proxy makes the connection to the real server. The Symantec scanner does
this. The anti-virus POP3 proxies have known problems with SSL servers.
Check the email settings in Outlook and see if the POP3 server was
changed to localhost or 127.0.0.1. If so, that's what happened. You'll
need to consult with the AV vendor to see if they have a fix. If not,
you can switch your clients back to direct connect to your real server.
Meanwhile, you can also install a server-side AV scanner. There's a free
one called the "Procmail Sanitizer" that runs as a procmail recipe via
sendmail and "defangs" dangerous attachments by adding an extra bogus
extension. This keeps clueless users from just double-clicking on
executable material.

Thanks for the feedback! I know that somehow it intercepts the email for
scanning but I'm not sure if this happens at the sockets level. The settings
are still pointing to the email server in this case.
I have an update: stupid user, I asked him to turn off the virus scanner and
then try it. He said he did and it did not work. Well, it turns out he only
disabled it but did not turn it off. Of course, when I finally turned it
off, the problem went away.

HI,
I could not find a mailing list to join , so I need to ask you. I am
currenlty runing RH 7.1 running a 2.4.17 modular kernel. I have
installed Postfix's latest realese on the system in a chrooted jail. It
all works fine sending and receiving. After I did the
CFLAGE='-O9" ./configure --enable-specialauth --enable-servermode
and then make, make seemed to stop at this point:
cd ./popper && make all
make[1]: Entering directory `/var/tmp/qpopper4.0.3/popper'

It may have not been in that order. I had to do a cut and paste joh.
I did the make install and after I tired to start the daemon I got the
following:
Jan 20 16:00:16 dopey /usr/local/sbin/popper[4603]: Unable to obtain
socket and address of client: Socket operation on non-socket (88)
Any help would be appreicated. Thanks in advance.

Be sure you compiled with debugging enabled. Try doing a 'make
realclean' and then re-run ./configure, adding '--enable-debugging'.

Are these active connections? Is the problem that connections are
hanging, or not going away, or that too many users are connected at
once? What does a process trace show?

Read on, they're covered. (In brief: they drastically speed up most
connections.)

Usually this is a harmless error that just means the client
disconnected without sending 'quit'. If it happens a lot or if
user's sessions are halted then there is some underlying problem.

Outlook has a relatively short timeout, and 80 MB is a lot of mail. On
first connection, Qpopper copies the mail spool while analyzing it for
mail headers. This can take awhile, and Qpopper won't respond to the
PASS operation until this completes. It sounds like Outlook is giving up
before Qpopper is done.

Depends on the platform. Qpopper uses the native user database,
typically /etc/passwd on Unix-like hosts. Use the tool that came with
your OS. (For Linux, there's useradd.)

Patrick,
I noticed by the list that you're a 7.2 user with Qpopper.
I wonder if it would be possible to ask you some questions?
First, I'm completely new linux and qpopper. My objective is to make a
personal pop3 server run.
My first question is: What directory should the downloaded files be place
in for decompression and loading?
On my first attempt, I made a directory /root/temp and I see that after
installing Qpop I have a directory /root/temp/Qpopper with all the files in
it. Will this location have an adverse affect?
I plan on reloading RH (Qpopper is the only thing I'm going to run) so you
input on the directory would be appreciated.
Also in the manual on page 9 there is an "IMPORTANT" reference "In the mail
spool directory, some systems have a symbolic links from /usr/mail to
/usr/spool/mail. Make sure you check this before install Qpopper." I don't
have these directories, and I not quite sure what the manual is telling me.
Should it be there or not? Your comments on this would be appreciated also.
Thank You.

For the extraction and compilation it doesn't matter where you put the
files (mine are in /home/bobkat/Qpopper4.0.3), you will end up doing a
make install to put he finished program in the correct directories, on
most linux systems the mail directories are /var/spool/mail so you don't
have to worry about those directories, I've been told by many a sysadmin
that you should use leveled (/var/spool/mail/m/username) mail
directories or put the mail in the users home directory to speed things
up, I continue to use the single directory mail spool myself (only 80 or
so users though). Have a lot of fun

Subject: .pop files in server mode
I've recompiled popper (4.0.3) twice with --enable-server-mode and
it's still creating .user.pop files that play havoc with the free
space on disk. I'm running under solaris 2.7 with sendmail 8.11.6. My
spool directory is /var/mail and a soft link to /var/mail lives in
/var/spool/mail for redundancy.
Popper is started by inetd as
pop3 stream tcp nowait root /usr/local/sbin/popper popper -sU
and .user.qpopper-options files for selected users live in /var/mail.
Any insight would be appreciated!

These files should not exist *except* when actually needed to recopy
the spool for updates during a session. Updating a spool file in-place
with insertions and deletions in the middle of the file, with no temp
file, would be pretty difficult; so even in server mode, temp files
will be created, but should be deleted at the end of a session unless
something is going wrong. If you also use the --keep-temp-drop option
when you configure qpopper, to keep the files, they will be kept around
for time-stamp purposes but should be zero-length files.
If they're coming and going - that's normal and pretty much
unavoidable. If they're actually sitting around taking up disk space,
something is probably going wrong on process termination when qpopper
tries to update them back to the main spool - try checking your logs,
and then try running a qpopper session with a trace file.

Hi,
I am using QPop version 4.0.3, I have the following issues :
1-I cannot access to a pop3 account while the mailbox is receiving
emails.
2-I cannot access to a pop3 account twice at the same time
Both gave me the following error :
-ERR [IN-USE] /var/spool/mail/.projects1.pop lock busy! Is another
session active? (35)
Thanks.
