Since your site appears pretty conscious about security, it just might be
your /etc/hosts.allow or hosts.deny file. If your site blocked off
accessing your host for pop from outside your net don't forget yourself,
i.e. is 127.0.0.1 (or your own IP) allowed for the pop3 connection?

Does the machine you telnet from have its IP reverse domain lookup set-up?
This disconnection appears like a tcpd action, perhaps the default
behaviour of your tcpd is to behave paranoid with hosts that don't have
their reverse lookups straight? Come to think of it, I think this is the
default behaviour of the new Qpopper.

It's not actually connecting. May not even be starting. Try starting the binary
by hand and see if you can telnet to it. What is the line that you have in
inetd.conf? What is in the log file? If you don't have a log file, then start
one.

I still suspect the tcpd wrapper program, because it shows something is
trying to connect (popper?)...then the trademark disconnect.
I would first try removing the tcp wrapper line from your pop3 command
string in your inetd.conf. Something like so, depending on what O/S you have,
# pop3 stream tcp nowait root /usr/sbin/tcpd in.pop3d
pop3 stream tcp nowait root in.pop3d
Kill -HUP your inetd PID, then try connecting to port 110. You should then
know whether your pop3 program actually works. If it works this way,
figure out what your O/S people did with the tcpd they installed in the
documentation. Suit it to your needs and re-activate the line in inetd.conf.

Depending on the OS and business of the machine, "strace -f -p<pid of
inetd>" can reveal the problem fairly clearly.

I have been running this mail server for about 3 weeks now but just last
week the pop server had been stopping randomly making it so people are
unable to check their mail.
since then I have been able to track down the error, the syslog reported
this error:

Seems a problem with tcpd. Have you changed something in
/etc/hosts.[allow,deny] ?
[yurj@caccamo yurj]$ strings /usr/sbin/inetd | grep failing
%s/%s server failing (looping), service terminated
Seems that inetd can't run tcpd or popper. Can you post the pop3 line in
/etc/inetd.conf?

hello.
are there any plans to implement AUTH authentication into qpopper? - as
described in

i'm keen on looking at secured authentication - i've looked at APOP but
from what i've read you need to keep a separate database for pop users and
system users - something that i'm not too keen on doing. of course i'm
more than happy to be proven wrong about this :)
anyone else been down this path and wanna give me some feedback?

Too many qpoppers starting in a short period of time. Increase your
inetd service limits.
default is 40 connects in 60 seconds.
pop3 stream tcp nowait.100 root /usr/sbin/tcpd in.qpop3d -s -T600
adding .100 to the end of nowait makes this 100 connects in 60 seconds.
Tweak to suit.

Subject: Re: AUTH authentication support to qpopper?
I think AUTH is CRAM-MD5. It requires a separate database too. It sort of
boils down to a few options (cryptographically):
1) Have plain text passwords go across the net and retain compatibility
with authentication databases like /etc/passwd. Here you get to have the
password on the server encrypted
2) Have a hash of the password go across the net and lose compatibility
with auth databases like /etc/password. CRAM-MD5, APOP, SCRAM and
DIGEST-MD5 are all in this category.
3) Use public key like SSL to secure the connection and then to
plain text passwords inside the secured connection. Here you get the best
of both 1 and 2, but have to a lot more to set up and probably have to
pay someone money because public key crypto is patented (until Sept 2000).
Personally I like #3 because I believe compatibility with existing
authentication databases is very important. Hopefully in a year we'll all
be doing this. Note that you can sort of get this behavior now with
qpopper unmodified if you use something like stunnel. We also have to
lobby to get more mail clients to support SSL. Usually it's a problem
because it costs about $1/copy to license the RSA algorithm, and that's a
huge chunk of the revenue.
The other thing is that there are two flavors of SSL for use with POP.
There's the alternate port variety that just does SSL right of the bat on
port 995 much like https runs on a different port than http. Then there's
the STLS (or STARTTLS) varient that negotiates it on port 110. The STLS
is politically correct to conserve our precious bodily fluids, I mean our
precious TCP port numbers. Different clients support different ones.
Stunnel gives you the alternate port versions.

FWIW, there are instructions on setting up/using SSH tunelling at
http://www.ccs.neu.edu/groups/systems/howto/howto-sshtunnel.html which
are easily adapted for any server running sshd.
There is a freeware SSH client extension for Tera-term (windows), which
removes the need for licensing fees in most cases.

No, qpopper does not reject connections from hosts which lack PTR
records. By default it logs this as a warning, but this can be
turned off.

Is anyone able to give any hints on speeding up qpopper? I have a Sun
Enterprise 3000 system which is heavily used as a POP3 server for many, many

server for the clients.
Does anyone have an ideas on how to tune things to speed up POP3 access? I was

Any ideas?

It's a great program, but your statement is untrue in the US. RSA is
patented, and may only be used freely iff you are using the RSAREF

regardless of what software product it is used in. Users outside of the

I've been using "ucspi-tcp" as a launcher for qpopper instead of inetd. It
still isn't fast enough for me, but maybe it will help you. You can find it

Try running configure with --enable-servermode. If you have no customers
that use pine/etc as local mail clients on your server (read the FAQ on
this) this is great for bringing a new lease of life into your mail system.

If you look at the man page for inetd.conf you will find that you can
change your pop3 entry from something like this:
pop3 stream tcp nowait root /usr/sbin/tcpd
/usr/local/lib/popper -R
To something like this:
pop3 stream tcp nowait.200 root /usr/sbin/tcpd
/usr/local/lib/popper -R
and stop those nasty messages. The number after the "." is how many
instances may be spawned in a 60 second period. The default is 40 I
belive.

Hello Janet and the list:
At my former place of employment, we had a similar issue. It was so
apparently random, and very rare, that we couldn't attribute it any
one subcomponent on our Solaris server (sendmail 8.9.3, Qpopper 2.53
or 2.52, Solaris 2.6 with all recommended patches as of June or so).
Then, we found one user who sent e-mails out that would cause the
problem everytime. The problem is not Outlook (Outlook has other
problems, but this isn't one of them AFAIK), as the reproducible
error was found to originate or result on Eudora clients and Outlook
alike. The sender was HTML formatting her signature, which had a
horizontal line in it. The horizontal line was really a bunch of
non-breaking spaces that were underlined (not an <HR> tag from HTML).
The client would send the message to sendmail and the signature would
disappear. When a client would POP their e-mail, they would get all
of the message, minus the signature. If another message followed,
then it would be catenated to the message. The signature would be
some unprintable character (both in the spool and when the client
retrieves it).
I am sending this e-mail to my colleague to see if he has found the
root cause yet. I will update here if and when I find out.

Hi,
I am new to maislerving and stuff. I have installed a package on my linux
machine which is a patched version of qpopper 2.53 to support virtual hosts.
I was wondering where I could find a tutorial on start to finish on setting
up qpopper? Do I need to do anything special to my dns server? I am just
trying to setup a fake web site locally. I have managed to do it cause I
setup the zone in my dns server and stuff. I am still kind of new to Linux.
I have only done easy stuff (ie: setup a router, web server, and dns
server). I am trying to now tackle the mailserver stuff. I was also told
that I have to have an smtp server even if I don't plan on sending any mail.
I just want to recieve it and have it stored in pop3 boxes for users to
check it. Could someone shed some light on this stuff? Thanks.

Subject: Re: Tutorials
Go to www.qualcom.com for information on the qpopper. I think they have some
docs there. You do not need to set up SMTP. it is not necessary. Basically,
qpopper will front end sendmail. sendmail will recieve on port 25 and store
incoming mail in /var/spool/mail/userbox until either it is read directly on the
server, or a pop3 client requests the mail via qpopper.you'll create the
customer accounts on the linux box for whoever you want to have a pop account.
that's a VERY brief rundown.

What's really needed is an identd persistent-style startup, where
qpopper runs as a master server and spawns children as new hosts connect
to it, rather than having to start every single process via inetd.
This should also bring some reduction in resource consumption by running
instances too, as they can inherit/share most parts from the parent
process.

Hi,
We had this problem also when we were running BSDI 3.x. The
solution is, if memory serves me correctly, to remove the
references to NDBM and GDBM. What you need is DBM only.
./configure adds NDBM and GDBM to the Makefile, but those don't
work.

Larry

it looks like this and many other problems could be avoided if messages
were kept in separate files; my MTA (exim) allows this but AFAIK qpopper
does not;
am I correct?
is it possible to configure qpopper to find messages in separate files?
qpopper could even check if /var/spool/mail/<username> is a directory or
a regular file and proceed accordingly..

No, unfortunately for some reason, send-mail has to resolve an actual domain. it
will not resolve to just an IP. There may be a way around it , but i believe
that involves recompiling it from scratch w/ modifications to the code. Unix
networking is very dependent upon host names, domains, etc.
As far as adding users, i'm not familiar w/ doing it via shado passwords, but if
you wanted to add a usr without the adduser command, you would make and entry
for that person in teh password file. when connections are made to teh pop
server, authentication is done by querrying the passwd file, or the shadow
password file. Of course don't for get to make them a home directory also.
I will probably be playing w/ this more in the near future. Anyone else any
comments?

Off the subject, I think....but has anyone noticed that qpopper
is a memory hog? We're running Linux 2.2.11 (which has a known mem
leak) but DAMN. if qpopper isn't running, it ain't that bad. Any-
one know why qpopper wants 1.5 meg per pop session?
I tried running qpopper RE 2.4x some time ago and gave up- it worked
fine for a semi-loaded server (our corporate mail- <10,000/day) but
absolutely fell over when used on our ISP email box. I still have
qpopper (2.5x) on our corporate box but had to fall back to ipop3d
for our ISP (5000+) boxen.
I moved to postfix (instead of sendmail) on our ISP box, and love it-
but I had to use qpopper for POP3 services (I hate that false message
ipop3d sticks in there)....and I find that STILL qpopper falls over.
Qpopper seems to suck any and all available memory (and I have 319MB)
and still whine for more. Admittedly, Linux 2.2.11 has a mem leak,
but my god. What the hell is it DOING with all that memory?

No it's just a matter of commenting out the DNS checks in sendmail.cf
or generating a new sendmail.cf and restarting the program.

This is more dependant on mailbox size than anything else...

One of my ISP mailservers handles 85,000 pop accesses per day vis
qpopper, however the mailboxes on that machines almost never exceed 2Mb.
It's only when someone leaves 10-20Mb on the server that I see problems.

Loading the entire mailbox in as it scans through to find the From lines

Bzzt, wrong, thanks for playing. Read RFC's and send mail to for example:
tmo at [212.160.209 dot 4]
or tmo@[3567309060]
or tmo at [212.160.209 dot 59]
or tmo@[3567309115]
or tmo at mail.biuro.net dot pl
or tmo at biuro.net dot pl
and have it end up on the exact same physical machine. You can also go
see my web page at http://2152961356/~tmo

Why the hell it load all the mailbox in mem? It should be independent
from the file size. It just take longer to send, but not take up memory.
Or am I missing something?

ha! wrong! just scan, without keeping in memory (just like grep)
here the scenario:
a) You load a block, scan for header info, remember them.
b) collect info
c) start send mail, reading from disk some bits, sending it and so on,
wothout loading all.
Yes, in c) you reread the file from the beginning, but it is most in the
buffer cache of the os, so it is very quick.

Subject: Unable to get canonical name error (Yes, I read the FAQ)
I'm runing Qpopper 2.53 and users are having trouble getting mail when
their reverse lookup doesn't work. I know this creates a warning in the
log files, and I know that 3.0 beta can turn the check off. I'm a little
confused though between generating an error, and having it outright fail.
It's fine with me if 2.53 generates an error, but can you make it the
email retrieval attempt go thru even if it DOES generate an error, or is
it built so that if you get a canonical name error, that's the end of the
story, and the user can simply not get the mail?
Thanks in advance for the help...

You aren't saying what is failing. Does the daemon die? Is the client
timing out because the DNS times out? Does the client crash?

this would probably be solved my having messages in their own files (as
someone mentioned before). And while I thought this was a good idea at
first there are some inherant problems.
A) You trade-off memory for file I/O time
B) Directory scans could be slow if there are lots of messages in the
directory and no indexing system is used.
C) and maybe the biggest problem, you can run out of inodes REAL quick.
we handle about 30,000 requests per day with a modified qpopper 3.0b
mailbox sizes usually dont get bigger than 4 MB.
server load (linux) averages at about 1.5 in the prime time hours

Subject: Re: Unable to get canonical name error (Yes, I read the FAQ)
Well, I suppose failling is not too descriptive. The connection to the
mail server drops. As in refused. Here's a little excerpt from the man
page on popper:
---
The popper program initializes and verifies that the peer IP address is
registered in the local domain, logging a warning message when a
connection is made to a client whose IP address does not have a
canonical name. For systems using BSD 4.3 bind, it also checks to see
if a cannonical name lookup for the client returns the same peer IP
address, logging a warning message if it does not.
---
After this, authentication happens.
Again, it sounds like there's just an error message. In my case, there is
an error message in the logs (the canonical name thing) AND the connection
is refused by the server, before authentication even kicks in, as can be
shown by telnetting to port 110 and watching it connect and then pop up a
box that says connection refused. I hope this additional info helps
out...

The basic problem with all email programs/protocols is that they are
designed for small messages and don't scale well.
Qpopper was originally designed in an era when anything larger than 64kB
was massive - and quite often wouldn't pass through gateways, so was
uncommon.
Nowadays, with people sending full audio-visual multimedia attachments,
64kB is commonplace, as are 20Mb+ plus inboxes.
Practices and design objectives need to change somewhat. The load of
a qpopper starting up is another area which needs addressing (forking a
new process vs spawning a child) in order to cope with current and
future environments.
No, I'm not a programmer, else I'd be offering more than just
suggestions.
As it is, I have my hands full maintaining the ORBS database of
abuseable email relays - spam and unauthorised relaying is another area
where email systems are taking loads they were never designed for and is
a direct artifact of the SMTP protocol being a product of an area when
network abusers usually faced court-martial.

Alrighty, I've emailed the list before about this, but it continues to be a
problem =(
I'm using qpopper 3.0b18 and we have a service for our customers so they can
check their email from anywhere via the web, this interface acts just like a
pop3/smtp client as far as the server is concerned, the only problem is
these people are gathering HUGE email files in /var/mail because they never
download the message, it gets read via pop3 then they just leave it on the
server.. qpopper is QUITE unfriendly to mailfiles of this magnitude. I am
already running in servermode and here is my inetd.conf line:
pop3 stream tcp nowait.400 root /usr/local/libexec/qpopper

this is true. when we DO get a complaint about not being able to retreieve
email, 9 out of 10 times it's because they're mailbox is x MB or bigger.
something needs to be done about this.

also true. popper process starts up from inetd, eats up 90% of the CPU,
and slowly decreases, but not nearly as fast as it should.
