Subject: Re: duplicate mails and slow mail
I'm guessing that the problem is external to your company given that
your queues are empty.
I'd check the "Received: " headers for date/time consistancy. Start at
the first one. Towards the end of the line is a date-time group.
Check this date with the next line. Perhaps only a few seconds
difference. So check the next one. A few more seconds? OK. check
the next one... Eventually, you probably will find one that is way
off...
However, you also have to take into account time-zones... One hour off
but coming from a mountain states ISP? OK...
Is the message coming from a PC that is off line when the message was
composed? The "Date: " line is composed when the message is queued for
delivery.
Just some thoughts...

finished sending data to it.

If by the term 'crash' you mean the program truly stopped, and Windows told
you the program executed an illegal instruction or some such, take that up
with Microsoft. If you mean there was an error displayed by Outlook, then
what you're talking about is NOT a crash.

You said something crashed. WHAT CRASHED?
You have not told us what you're running for a config, most especially for
TLS issues. Please provide enough information for folks to help you.

seems like if you only allow mail from list members you wouldn't need
this...I suppose it protects against errors though...You could have a
max attach size too of something reasonable...
it's just unexpected is all, no matter I suppose, but if I hadn't read
the list mail I would never have noticed that my attachment wasn't

I didn't say it would stop them from crashing. They're buggy programs.
What *should* have improved is that now they should not be locked out
of the spool file for several minutes as a result. That "I/O error"
message above indicated that qpopper now detects that the client has
gone away so that the mail spool should be back in place immediately.
> HELP please...
You'll still need to track it down to what message or messages in the
mailbox cause them to crash; I would start by looking for viruses or
for spam messages with large attachments and deleting those.

Thanks to the latest worm programs, it's necessary to block attachments
even from subscribers. Unfortunate...
I saw one of the diffs come through in one of the emails yesterday, though
QuickTime claimed it owned the file type.
Best bet is to push stuff into ascii text and just put it in the body...
safer for everyone.

There's code in the next release of qpopper to give up more quickly when
detecting the TCP session has been terminated by the other end, which
should help some. I've been running with those mods for a while.

It would appear the problems are between Microsoft and the email, and the
only issue with qpopper is in how quickly it releases the mail spool after
a client program croaks.
I'd say Microsoft is probably the proper place to go for support. Perhaps a
newer version will fix the problem (though it'll doubtless introduce others).

I prefer NOT to see attachments on a mailing list. The bulk of
subscribers won't need to look at it, so it's a waste of bandwidth.
Better to send it direct to those requesting it, or post it on a web or
FTP site for download by those who want it.
If it's a small text-only patch comparable to the size of mail headers,
then just post it inline.

Check the 'Received:' headers of the messages, to see what times they
were processed by your SMTP server. Also check them (and the
'Message-ID:' header) to see if the messages were sent separately or
were duplicated en-route.

Even better: post the attachment on an FTP site and include the URL

Subject: qpopper & qmail -ERR[AUTH]
Date: Thu, 6 Dec 2001 12:29:56 -0700
Hi - I'm new to qmail and qpop (done sendmail for a while)
I get the following entries in /var/logs/maillog
Dec 6 14:12:03 tugger popper[30808]: apop "username"
Dec 6 14:12:03 tugger popper[30808]: username at

Dec 6 14:12:05 tugger popper[30874]: Stats: username 0 0 0 0
zzz.erprises.com 63.xxx.xxx.xxx
I'm particularly interested in the "-ERR[AUTH] not authenticated"
part of this entry.
qpop was configured with the following:
./configure --enable-debugging --enable-specialauth --enable-standalone
--enable-home-dir-mail=Mailbox
So that it would read the shadow password file, run standalone, and use the
qmail ~./Mailbox directory structure.
Where have I gone wrong???

Subject: problem using qpopper+mysql
Date: Tue, 11 Dec 2001 00:41:38 +0100
Hello,
I have to move a mail server to a new linux box
and I'm having real trouble now:
First I wanted to install the latest qpopper-4.0.3
which works perfectly as long as I don't activate
the mysql-patch I found.
As soon as I compile with the --enable-mysql
switch qpopper just quits after the connection
has been established by inetd.
I can't seem to get any debugging message
(yes, i tried to compile with --enable-debugging).
When I try to connect using telnet it looks like that:
/usr/lib # telnet linuxbox pop3
Trying aaa.bbb.ccc.ddd...
Connected to linuxbox.
Escape character is '^]'.
Connection closed by foreign host.
/usr/lib #
So I tried to use the very same qpopper/mysql-version
that I used on the old box (qpopper3.1.2 + exim-qpopper-mysql-0.11.2)
and I find the very same problem :(
what's going wrong?
help, anybody?

Subject: IO and SSL errors
I have qpopper 4.0.3 running from inetd on an alternate port and using
OpenSSL. Some users seem to be able to connect fine, but others are
having intermittent problems. One in particular is using the latest
Eudora, and sometimes when she tries to get mail I see a string of
errors in the logs. For instance:

So a TLS login seems to go OK, but then almost 10 minutes later,
there's an IO error.
Now, looking at the FAQ, I suspect this may be solved by changing the
chunky write option, but the FAQ suggests setting it to TLS. Since
my problem occured while using TLS, I've changed it to never.
So, the questions are: 1. Is this a network congestion problem or
something else? and 2. Is setting chunky-writes to never a good idea
or am I inviting other problems by doing this?
Thanks for any insight, and feel free to ask for more info if that
would help.

Well not all of us are using sendmail, but any way...
You haven't provided much information on the attack, so not all suggestions
may be valid.
1) Block, temporarily or permanently depending on the importance to you of
sending mail server, the source IP number(s) at your border router or
firewall.
2) I'm not sure whether sendmail is running from inetd, but DON'T block as
in 1) with tcp wrappers as your inetd will probably start looping and
failing if you do.
3) Provide as much data as you can to the ISP sending the mail to you and
ask that they assist in stopping it asap.
4) As above but with your upstream provider, to stop it arriving to you.
5) See if you can track down the open relay server and attempt to get its
maintainers to close it.
6) You could investigate whether, like qmail, sendmail has a badmailfrom
option to reject messages, based on sender's name. However the places at
1) are arguably better for dealing with the workload.
HTH and good luck.

Apologies to you and all, but I am not sending the original message

Having been alerted to this, I have already requested that the listmaster
sort this out as the problem seems to be at their end. (I for one have not

10...)
This is of course particularly ironic since I was giving advice on how to

Can other users authenticate with APOP, or do they all have trouble?
Can this user authenticate with a different client (but also using
APOP)? Have you tried resetting the APOP password?

You can try enabling debugging in the client, to see if that helps.
Or try a packet trace if you can reproduce it. You can also try
increasing the client timeout, as a test.

It could be network congestion causing dropped packets and retries.
Chunky-writes in this situation can lead to timeouts. A packet trace
should make it clear.

It's really an efficiency issue. TLS/SSL has overhead per-packet, so
it makes sense to send fewer large packets instead of lots of small
packets. But if you're having network problems, try it.

Subject: QPopper Optimizations with IMAP
I wish to use Qpopper with WU-IMAP. This works fine, however,
I would like to use some of the optimizations of qpopper,
like server or fast modes. The server (linux) runs only
sendmail, qpopper and imap -- no shell connections.
The Qpopper documentation does not really state whether IMAP
can be run in conjunction with either or both of qpopper
optimizations, and what would happen if they were enabled.
It just says that there shouldn't be anything else that modifies
the spool files...but sendmail does...so maybe IMAP is ok...
I assume that this is a fairly common configuration. Can
anyone shed some light on this?
Thank you very much,

There's a known bug when running qpopper on OpenBSD. The socket handling
code in qpopper triggers a bug in OpenBSD. There was a thread about this on
tech@openbsd about a month ago, but I haven't heard any developments since
then. It will work fine if you run qpopper through inetd, so I'd suggest
doing that as a workaround.
Another thing to note is that with OpenBSD, you have to force DES passwords,
as OpenBSD defaults to blowfish, and since there's no PAM in OpenBSD, qpopper
has to do the authenication itself. I was working on a patch that would
provide support for blowfish and MD5 crypt replacements, but I haven't
finished it yet.

Subject: force clean mail after reading for specific users?
We run qpopper 4.0.3
I know that this version has the option of defining for
individual users that no temp file (.username.pop) be created
for him when he accessed his mail (i did it by creating a file
called .username.qpopper-options under the /var/spool/mail directory)
It'll be even more useful if somehow we could force for some user
that when he has downloaded his mail to his pc pop client machine,
that the mail which is left on the mail server is cleaned as well
(We have many many users who just leave several 100 Mb of mails
without deleting them)
I doubt if this is possible or not

What you're looking for is SMTP AUTH, which has nothing to do with
Qpopper. Qpopper is POP3 server software, not SMTP server software, so it
is responsible only for delivering mail from the mail server to your
users' POP3 mail client software. Mail sent the other direction - from
your users' POP3 mail client software to the mail server - is accepted by
your mail transport agent (your SMTP server software), not by Qpopper.
If you're using a Solaris box, the MTA is probably Sendmail. Recent
versions of sendmail (8.10 and later I think) can be compiled to use SMTP
AUTH. You're probably using the SMI distribution of sendmail, and AFAIK
there's no way to add SMTP AUTH to that. You'll need to download the
source code from www.sendmail.org and compile it yourself.

It's be neat to have clean hooks to replace the /etc/passwd
based authentication with an external one (perhaps via #define?).
MANY platforms don't have PAM and those that do, are sometimes
not quite compatible.
Being able to cleanly pull the auth out into LDAP (for example)
would be a boon. I've done this before for 2.5, but not the
current code base.

PM,
I run a Perl script called trimmail which is set by cron to run every
night. It goes through every user's mailbox and trims out unread messages
that are older than 30 days and read messages older than 3 days. I this
way, my users are happy and I get to keep my hard drive clean. If you want
a copy, just send me a message.

There is a fix for the OpenBSD bug, but I'm not sure if it is in
OpenBSD current or where. There is also a work-around that's in the
Qpopper current, so will be in the next release.

This would be useful, for several reasons. There are people that
prefer to run with all mail users defined in a database, for extra
security and/or to avoid limits on the number of users on some
platforms. The security aspect alone is compelling, as Qpopper
wouldn't need to start as root anymore. Probably it should be done
as a ''--with-foo" ./configure option that causes Qpopper to link
with a supplied library and call standard functions.

Subject: openssl on AIX?
Qpopper experts,
I am running openssl on an AIX4.3.3 system. I successfully compiled
qpopper. However, I can't seem to create the proper certificates given the
example on line. Note: AIX does NOT support a /dev/urandom
generator. Hence, the very first openssl command fails:
openssl req -new -nodes -out req.perm -keyout /etc/mail/certs/cert.perm
I am guessing that I have to use genrsa with the -rand filenames
function in order to generate the keys.(?) Has anyone created keys on AIX
for qpopper? If so, can you share with me your steps for successfully
creating the necessary cert.pem file (self signed preferred)?
Thanks!

I'm curious... I can't find anything in the install/configure process that

BLOCK_UID to 10 if it's not already set. On the systems I work with, the
BLOCK_UID should be set to 100.
I guess it'd make sense if configure allowed this to be configured...

Subject: Qpopper loch mechanism
Dear folks,
I have a question about Qpopper's locking mechanism (3.x). I have a Perl LDA
on my FreeBSD 4.1.1 box, in which I use an exclusive flock to lock a user
mailbox before writing to it. I always thought qpopper honors the same
flock, and will not truncate on the user's mailbox until it can acquire a
lock. But since I suspect to have lost some mail, I want to be sure now.
I know that (additionally?) qpopper uses the .user.lock and user.lock file.
Should I try and emulate that, or will an flock on mbox suffice? Basically,
all I need to know is which one should I set to prevent qpopper from writing
and/or truncating mbox.
Any clarification would be highly appreciated,
