Double Mail Feature

Hi Paul,

some of my customers having problems getting double or triple Mails, the
header is exact the same.

Would "suppress_duplicates" help in this case?

Could the logging a bit more informative

because this line doesn't help anyone:
Notice:[message] sort_deliver_to_mailbox(+2157): message id=5015749,
size=3093151 is inserted

The only relevant information is the message id, but the userid and the
mailbox id would be great too.

One other thing.
start-stop-daemon --stop --signal HUP --quiet --pidfile
/var/run/dbmail/dbmail-imapd.pid
doesn't reopen the logfile so the debian init script is not working. Is
there a other way to reopen the logfiles?

thx

this may happenif LMTP dies before the message is completly
received from the MTA beause the MTA loses the connection
and tries again, depending at which moment that happened
you get mails more than once, but better than missing ones

maybe *but* it only masks the problem with is not good over the long

lmtp is not runs fine, no messages in the log and the monitoring system
doesn't restart the daemon so I think it hang up the connection without
writing it to the log.

It would, but question is why the message is delivered more than once.
suppress_duplicates is meant for filtering out cross-posted messages,
not for solving generic delivery problems.

I think restart is the only way, atm.

Yeah thats the question...

I changed the loging level to info but the floods the log with ci_readln
dumping the complete message.

[0x19b1200] Info:[clientbase] ci_readln(+440): [0x7fe2e76df010] C <
BLABLABALBALBLABLALBALB

I think that would be better in "debug" level because the log gets really
big in sort time and I can't read the log anymore ;-)

Re: Double Mail Feature [In reply to]

Ok I have some more log lines.

This is postfix:
Jul 29 17:11:50 mailgate postfix/lmtp[1052]: 248ED202D8:
to=<t.name [at] example>, relay=172.22.14.195[172.22.14.195]:24000,

connection with 172.22.14.195[172.22.14.195] while sending end of data --
message may be sent more than once)

This is lmtp:

The best part of it is that the same message was sent to multiple users on
my server all other users has no problems only this one guy.

This user has no sieve script and has no quota.

The lmtpd log looks pretty normal to me. Perhaps you can increase
logging at the postfix side:

postconf -e 'debug_peer_level=2'
postconf -e 'debug_peer_list=172.22.14.195'

and once you're done:

postconf -e 'debug_peer_level='
