2.2.14: lmtp segfaults

dbmail-2.2.14 seems to have some problems in lmtp-daemon additionally
to wrong from/to in autoreplies

until now it dies not fully but there are too much segfaults for the few hours
running on Fedora 11: 2.6.30.10-105.2.4.fc11.x86_64 #1 SMP Tue Jan 19 22:46:59

Re: 2.2.14: lmtp segfaults [In reply to]

Harald,

apparently there's something in those messages that is tripping up
lmtpd. If you could provide me with one or two of them, I can reproduce
this and fix it.

thanks,

2.2.13, the same package as before even after a new "rpmbuild -bb"

Ok, that narrows down the changes that may have introduced this problem.
I'm on it.

Have you committed a patch for this yet? If so, which one fixes this issue?

Does this problem bite you? If so, please sent me a message that
triggers it.

I havent (yet) been able to reproduce this myself on my main production
systems (running 2.2.14).

Not at this time. I was researching pushing an updated dbmail into
Fedora but this caught my attention and looked like a good enough reason
to hold back and wait for a patch.

I see.

I used the testlmtp.py script from the master branch together with an
export of a spam box to put some pressure on lmtpd.

I've managed to track down two segfaults in the delivery chain. One was
indeed introduced by the recent revival of native autoreply. (thanks
Harald).

Re: 2.2.14: lmtp segfaults [In reply to]

Hi paul

Do i understand right that you don't need sample mails anymore
This would be really gladful because i can reproduce this only
on our live-machine and if it happens take the file from
/var/spool/postfix, but i would not prefer this because someone
could kill me while playing with customer-services :-)

Anyways, if you really need samples i would do this at weekend
followed by a downgrady after copy the spool-files

Regards
Harry

Harry,

Correct. For now I don't need any samples. Like I said, I've setup a
stress-test lab for dbmail22 using the tools from dbmail2.3. It's just a
matter of feeding dbmail-lmtp lots of different garbage and see if and
where it bails out.

Don't worry. However, should some messages get hung up in the queue
after I release 2.2.15, you can easily pull them out using mailq and
postcat -q <QUEUE_ID>.
