We use Dovecot on a cluster (10'000 domains, 30'000 account) without
any problem with pop/imap. We use Dovecot 1.0 RC10
Now we use virtual transport from postfix for mail delivery.
We need the Dovecot LDA for sieve support.
We test this solution on some domains with success.
But if we change the configuration of all our domains, we have a lots
of bounce with this error in postfix log:
postfix/pipe[24573]: 4F6D7CF11: to=<info at XXXX.com>,
relay=dovecot, delay=1200, status=bounced (Command time limit exceeded:
"/usr/local/dovecot/libexec/dovecot/deliver")
If I watch the deliver activity with ps/awk/watch, I see that if
deliver duration time exceed some seconds, the deliver process stay in
memory but do nothing. Here a strace output of this case:
Process 349 attached - interrupt to quit
gettimeofday({1161965973, 768478}, {0, 0}) = 0
poll(
Strace output nothing before the SIGKILL from postfix (command time
exceed 1200 second), the end of the strace:
[{fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=9,
events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 2147483647) = -1
EINTR (Interrupted system call) +++ killed by SIGKILL +++
I'm not sure is this problem has a relation with our deliver problem.
But in the deliver log /var/log/dovecot/deliver, I have a lots of
message:
deliver(info at labomex.com): 2006.10.27 18:29:28 Error:
file_dotlock_replace(/var/mail/labomex.com/mails/info/.dovecot.lda-dupes)

Our dovecot.conf (lda parts):
protocol lda {
postmaster_address = postmaster at clm.net4all.ch
#hostname mail_plugins = cmusieve
mail_plugin_dir = /usr/local/dovecot/lib/dovecot/lda
sendmail_path = /usr/sbin/sendmail
auth_socket_path = /var/run/dovecot/auth-master
log_timestamp = %Y.%m.%d %H:%M:%S%t
log_path = /var/log/dovecot/deliver
info_log_path = /var/log/dovecot/deliver.info
}
We use on UID/GID per domain so every account of a domain use the same
UID/GID.
The mail storage is on a Debian Sarge NFS server with 2.4.27-3-686-smp.
Indexes are stored localy on each POP/IMAP/LDA server.
I don't understand why we have this problem. If somebody can help us,
thanks a lots.

After a lots of test, I found that deliver (LDA Dovecot) put the message in the mailbox of the user, but the process dont quit. After the max command time (from postfix), postfix kill the process, return an error in the log and bounce the message. But always no idea, why this deliver process dont quit after delivery.

So my guess would have been that dovecot-auth is busy and not answering to our requests.

Something seems to be overriding or deleting the dotlocks.. Probably because the deliver hangs for a long time somewhere.
