Zombie pop3s (and imaps?) processes in connect state

by Christian Balzer

Hello, we've been using perdition as a pop3/pop3s/imap/imaps proxy for about four years now, first with Debian Sarge package and now under Etch. And throughout this time I've seen pop3s (and from the looks of it the same happens with imaps) processes stuck in connect, like this: --- 16836 ? S 5:31 0 120 32179 2204 0.0 perdition.pop3s 28070 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect 7782 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect 24468 ? S 0:00 0 120 32311 1568 0.0 \_ perdition.pop3s: connect 14180 ? S 0:00 0 120 32311 1568 0.0 \_ perdition.pop3s: connect 13503 ? S 0:00 0 120 32311 1564 0.0 \_ perdition.pop3s: connect --- They never die off, keep the connection open, there is no traffic and the other end might be long gone. Last trace in the logs is always like this: --- Feb 5 22:05:16 pp11 perdition[7782]: Connect: hi.mi.ts.u->203.216.5.113 --- It must be something related to the SSL'ness of these service, since I'm not seeing this happening ever for imap/pop3. Alas a lot of people do use TLS with those, so it's not a generic SSL issue. Maybe the master process could kick a child handling connections in the head after "timeout" seconds in connect state? If more information is needed I can try to provide it, but note that with a rate of roughly 35 pops per second I'm a bit weary to turn on debugging. ^_- This may or may not be related to another SSL related issue, which will be for the sake of making searches in the archive more likely to find good keywords in a separate mail.

Problem bridging IMAPS to IMAP real server

by Jean-Christophe PAROLA

hi, I use Perdition perdition-1.17.1_6 on FreeBSD 8.2 witch mysql option. I want bridging IMAPS connection (993) to Perdition on IMAP (143) to real server and POPS (995) connection on Perdition on POP(110) to real serveur. All ports is setting to NULL in database I activate SSL with: ssl_mode ssl_listen I generate certificat thanks to man documentation 993 port is open but Perdition call with real server on port 993 instead of 143. The bridging works fine if i set "port=143' in database but the POP proxy don't work. Could you help me to find my mistake ? thanks a lot (i'm french and bad english...sorry)

Problem with external Real Server

by tobi

Hi all together my first post, so hopefully I do not ask something that has already been asked several times :-) I installed perdition on my server and it works very well for my local dovecot. clients can connect and perdition connects to the local server. So far perfect :-) Now I thought that I could connect from perdition to other external servers as well. So I set an entry in popmap for user(a)domain.tld to point to server imap.domain.tld:995 But when I check the logfiles I can see that perdition cannot connect to the external server. Although I can ping the server without problems. One strange thing in the logs is that as protocol always IMAP4S is used, even if port 995 would demand for POP3S. How can I achieve that perdition connects via POP3S to a real server, although the initial connection to perdition by client is based on IMAP4S. I tried to setup the real server as well with port 993 in popmap so port and protocol should match. but that did not work either. Thanks for any idea on how to solve that Cheers tobi

Perdition being far too chatty in the mail warn and error logs

by Christian Balzer

Hello Simon, if you're still/again in Tokyo, how did you like the snow this morning? ^o^ Debian Squeeze, thus Perdition 1.19~rc4-2. This version will log any and all session close activities to mail.warn and mail.err. Aside from wasting disk space (not really an issue here) and making the files pretty unreadable (I'd expect to find only a few lines of actual problems if any happened in there) the logging to mail.err is particular troublesome as this log file by default will be synced after each entry. And I'm dealing with 20-50 sessions per second here. Would be nice if this could be remedied. Looking at older (1.17) logs I'd suggest that "Closing NULL session" doesn't belong into mail.err, probably not even into mail.warn.
