Can I add my weight to this too - Solaris 2.6, qpopper 2.53. Had thought
that the problem was a combination of dumb users (sending the message
more than once), and network/server timeouts with Outlook Express as the
client if the message can't be sent immediately. Seems as though there
could be other reasons.
Our mail server is under extreme load (especially Friday afternoons, for
some reason) for a significant part of the time. What I haven't pinned
down is whether the duplication arises with sendmail generating the
message more than once into the mailbox file, or the during the download
process with qpopper.
We don't have that large a population (about 800 on a LAN) but the Sun
is quite old and is gamely fighting on against all odds!!! Maybe next
financial year .... there'll be a budget to upgrade it.
POP-wise we've advised users to check for mail every five minutes or
more - this generates about 20 requests per minute as most have a 30min
check in place. The main load is sendmail and the virus checker.

You can use the 'procmail' program to forward to another account, and
still retain mail in your local account, as follows:
.forward:
=======================================================================
"|exec /usr/local/bin/procmail"
=======================================================================
.procmailrc:
=======================================================================
PATH=/bin:/usr/bin:/usr/local/bin
MAIL=/var/mail/mnogales
MAILDIR=$HOME/Mail #you'd better make sure it exists
DEFAULT=$MAILDIR/mbox #completely optional
LOGFILE=$MAILDIR/from #recommended
:0 c
! mnogales at harpo.rediris dot es
:0 A
$MAIL

RPI has about 8k active POP3 accounts running on AIX
(about 500k POP3 and KPOP sessions a day)
and I have not seen the duplication problem on our server.
But, the geology department runs a small NFS (not POP3)
server on solaris and I've seen it there. Also, prior to moving the
server to AIX, we ran on a SPARC/20, where file corruption
was a constant problem (althogh no duplications). This
was solaris 2.4.
It is still possible that solaris servers so outnumber other
servers that the problem shows up there more often by chance.
But, I've suspected a problem with Solaris flock semantics
(as used by popper) for some time. Has anybody tried
duplicating this problem by running two poppers at once?
BTW, the suspicion arose when I noticed that flock was
not working correctly in a Perl script. The script is to remove
old, read messages from mailboxes It duplicates qpopper's
locking proceedure to lock the mailbox. It didn't work on
solaris, but worked fine on AIX.
Try the attached Perl program (you may have to modify it for
your file location). When a mailbox is locked, popper should
fail connections.

Subject: Re: One- or two-level mailspool hashing ?
We went from no hashing to two level hashing. There are about
8k active accounts, a little under 13000 passwd entries. One
level created too many large directories, as you said.
Note, popper 2.53 does not hash the pop lock file. I recently
tracked down some mid-day slowdowns (some of them
severe, with over 300 backlogged poppers) to a bottleneck
on the poplock partition when users with large mailboxes get
new mail (requiring a two copies of the mailbox, to and from the
poplock directory). Yesterday I installed new version of popper
which does two level hashing of the poplock file. Since this is
spring break, I won't really know if it's had any effect until next week.

We're having continuing problems with HP-UX 10.20 that are similar, but
perhaps not the same. The users perceive that messages are being sent
to them multiple times, but in fact it's just that the popper daemon is
dying on certain fairly large messages with large MIME attachments.
Beta 36 has, by one report, improved this.
If, in fact, your messages are actually being duplicated in the file,
then there are several possibilities.
(1) They are actually arriving multiple times, because your 'sendmail'
dies before the final handshake, but after delivering the message. The
remote 'sendmail' thinks it has not been delivered, and tries again.
Check your 'sendmail' logs.
(2) Your .username.pop file is not being deleted, so next time, the two
are concatenated.
(3) Your locks are not working, so two processes can have the mail file
open at a time. One saves all of its messages back to the mail file
while popper has its messages in .username.pop ... and then, when it
writes them back, they get duplicated.
(4) Somehow, message deletes are not taking effect.
(5) Something completely different.

Most probably. We have seen the phenomenon happen with a variety of
POP3 clients and without any new message deliveries taking place.
A simple mailbox check can have the duplication effect.
It is load-related and may very well be a locking issue with Solaris.

First, /etc/.forward won't work unless local-user's home directory is
/etc/, or you have included /etc/.forward in the ForwardPath in
sendmail.cf - which is NOT a good idea, since then EVERYBODY'S e-mail
is forwarded that way.
Second, ISTM that, at least at one time, this caused a loop if this was
the local-user's ".forward" file. I don't remember whether the result
was a hung delivery or no delivery. But it was probably not a correct
delivery. Can you demonstrate that this now works correctly with a
single user's .forward file?

Looks like you have a typo ('stutus' vs 'status').
Try doing dot-locking, which is the preferred locking method for mail
spools on Solaris. You can call maillock() and mailunlock() on
Solaris. On other platforms, Qpopper 3.0 has its own versions of
these.

So I did. Wonder why perl -cw didn't report that. Regardless, that
would not effect the lock. The "my" statement is just habbit.

To be sure "local-user" is not interpretated by /etc/alias or some .forward you can add a backslash before the address in the .forward file.
Example:
\local-user
remote_user at xxxxxxxxx dot xxx

i think the problem is possibility 3
the popper i have, does delete the .pop file after
the session is finished, but if the user access again
very soon, the .pop file hasn't finished to get back

Subject: forward
If you use Sendmail, I believe that you can also put a line like
forwarded-address at foo dot com, \account
in the .forward file, where "account" is the user account. The "\"
causes mail to be delivered locally to that account with no further
alias or .forward processing.
This is from memory, so I could be wrong on the syntax. But it is
possible.

Subject: RE: mailboxes getting duplicated
I have qpopper 2.5.3 on a solaris box 2.6 getting intermittent problems
also with dup'd messages. I am not running server mode. I have not noticed
the problem since I did the following:
I also did have a bottleneck problem with my Sun box. I found it to be the
NIC running 100mbs at half duplex. I added a startup script in rc2.d to
force the NIC to run 100 at full duplex and turned off auto negotiation. I
have also since upgraded Sun's sendmail to Berkley's Sendmail 8.9.3.
I don't know if any of this was relative to the problem but as of the last
two weeks when I implemented the changes I have not had any problems.

For many years sendmail has done the correct thing here, which is to
save a copy in the default mailbox as well as forwarding a copy. So
this is the easy way of keeping a copy of a message.

I've done some really big mail systems, and if the hashing is well
conceived, you can do a REALLY large number of mailboxes with a single
level hash.

On a FFS/UFS based file system, yes that's too much for comfort IMHO.
On a high performance file system that hashes its directory lookups
(like VxFS or XFS), 2k files/directory isn't nearly as big a problem.
My question is, why confine yourself to mailbox name letter hashes?
Why not run a simple (and fast) hash algorithm over the name, generate
a number, modularly divide by a prime and use that as the basis for
locating a mailbox? The main downside: You need a tool to find a
particular mailbox, but that's pretty trivial.
Let's pretend at some point you may grow to as many as 40000 mailboxes,
and you want to split these up nicely. Maybe that's about 250. Let's
use 241 because that's prime. Let's also number these hash bins 0 to
240 and make them in /var/mail.
Now, each time the LDA or popper go to modify a mailbox, they perform
a calculation on that mailbox, something on the order of:
PRIME=241
x = ?
y = ?
for character_position in lengthof(username)
do
n = ((n<<x ^ (n>>y))^(character_position)
done
bin_number = n % PRIME
Set x and y to be some small primes, and you're all set. You should
get a fairly flat distribution of mailboxes per directory. For 22k
mailboxes, I'd guess you may see between 50 and 180 files per directory,
a range that will flatten as the number of mailboxes grows. Note, if
you've chosen x and y fairly well, the hash will be quite good, within
20% in terms of flatness of what you'd see with a MUCH more expensive
hashing algorithm like MD5, for example.
For much information on these sorts of hashing algorithms see Knuth,
Volume 3 if I recall correctly.
This is less intuitive, a little more difficult to code (but not much),
can support hundreds of thousands of users on a one level hash, and
will give you much better balance.

I think the answer is the same reason why the Unix mailbox format is
so popular, despite the performance (and other) issues: people know
the format, and are used to being able to grep it and run other tools
against it.

Here this is the way I do it (Linux, sendmail 8.9.3, procmail):
In the home dir of a user I put .forward file that contain his/her
username and the remote address that s/he wants.
It works.

Because it's by default catered for by Qpopper 3.0 and Procmail 3.14,
leaving only UW IMAPD 4.7 to be slightly modified.
I prefer local patches to *one* package over site-specific patches to
three.

Hi,
Got a couple of questions. I'm running qpopper 2.53 and am having a (rare)
problem of a user gettig a SIGHUP or SISPIPE error messafe and having their
spool file hang around after disconnecting. According to the FAQ, it's
recommended to upgrade to qpopper 3. Version 2.5.3 is the current release
version, 3 is still in public beta. We are an ISP, our customers rely on us
for their E-mail and I hate to run beta software in a production
environment. Anyone got any thoughts on this?
Also, is there any future plans to make the archives of this list at
http://www.pensive.org/Mailing_Lists/Archives/qpopper/index.html
searchable, or is there a searchable archive somewhere else?
Thanks,

I think there's something wrong with the qpopper 3b36
at some moment at time it gives some user, for some
unknown reason, error:
-ERR [SYS/TEMP] Unable to open Bulletin database; contact your administrator
and then all the rest of the useres, trying to check their mail,
get the same error, and no one can get their mail
downgrading to 3b34 solves the problem...
("normal" pop functions + bulletins are working fine)

If you use Qpopper 3.0, you can add '--enable-auto-delete' to the
=2E/configure line. This causes all messages to be marked for deletion
when downloaded. If you do this, you should notify your users in
advance, to avoid unpleasant surprises.

Good afternoon all,
have any of you figured out how to couple qpopper with mysql on Solaris. I
looked at http://www.netd.co.za/mysql_mail and
http://www.kies.co.kr/~jhpark/Sendmail/index.html. The former uses exim (not
interested) and the latter has been tested only on Linux. Any ideas,
patches, pointers would be most helpful.

If you are going to run in normal mode, the following hardware is
required to avoid taking a serious performance hit on the server:
Additional-- over and above current drive controller and drive:
1 moderately sized extremely fast hard drive
1 high efficiency drive controller (Caching controller preferred)
OR
Large amounts of RAM and a RAM drive for the temp files to be written
out to. (must make sure it is large enough to accommodate several of
the largest mail boxes at once if people store message on the server
for a extended period)
You users will thank you for not being I/O bound...........
