Postfix > DBMail 2.2 (lost connections)

Hi There,

After our "forced upgrade" of the os and dbmail from stage/dbmail_2.0
to etch/dbmail_2.2 we are seeing this sometimes in the mail filter
log:

Mar 11 17:32:21 mail-in1 postfix/qmgr[31948]: BAE4B482F9:
to=<clients [at] emailaddress>, relay=none, delay=0.08,
delays=0.06/0.02/0/0, dsn=4.4.2, status=deferred (delivery temporarily
suspended: lost connection with
210.OUR.DBMAIL.SERVER[210.OUR.DBMAIL.SERVER] while sending end of data
-- message may be sent more than once)

And there are multiple copies of mail going into mailboxes. I havent
the foggiest where to start with this one?

Any pointers?

Thanks,

Simon

Log into db logs. Maybe too many connections concurrently?

Increase the logging level on the lmtpd server. Set trace_level=5 until
you catch above error, and send in the resulting logs.

I have set the trace log and i think it is a collation issue in the
database... my tables are still set to latin. Could this be the issue?

I have the trace of several emails going into dbmail, some of which
had the above issue:

http://devtga.newmedia.co.nz/dbmail_trace.txt

(I will remove this after ive solved the issue and i reported back to the list).

Thanks

Simon

Looking at the logs I see:

Mar 12 08:11:40 mail-store1 dbmail/lmtpd[3544]: Info:[delivery]
pipe.c,send_mail(+144): opening pipe to
[/usr/local/autoresponder/autoresponder.php]

Is that script accessible?

No - not as yet as we are recovering the data on the old VM at the moment.

As you might guess, this is our auto responder script. In the
dbmail_aliases table we have two entries, one to deliver the mail to
the mailbox and one for the auto responder (for the clients who have
auto reponders on).

Do you think this could cause the issue?

Update on this. I created a blank executable so make sure that there
was a script avaialble, but that didnt work. So i removed the entries
in the dbmail_aliases table and now we have no more errors.

However: We do need to make this work again. Is there a trick to
delivering to external scripts in 2.2?

Thanks

Simon

Re: Postfix > DBMail 2.2 (lost connections) [In reply to]

Delivery for external scripts in 2.2. works just the same as in 2.0.
However, autoresponders are much better written in sieve. But of course,
external scripts can do lots of stuff sieve can't.

Apparently dbmail fails to detect the missing script. That is a bug.
However, you can work around this by making sure the script exists, is
accessible for the dbmail user, and will execute as part of a pipe: by
testing that

will work.
