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.

updated IPv6 patches for perdition and vanessa socket lib

by Antonio Querubin

The original IPv6 patches I submitted earlier didn't build on Linux systems. Attached are updated IPv6 patches which have been tested successfully in inetd mode on CentOS 5. However, in daemon mode under CentOS, sometimes the spawned process will segfault. I'm still trying to determine whether this is due to a problem with the patch itself or the way I've built the RPM. Both daemon mode and inetd mode under FreeBSD seems to work reliably though so I suspect this problem is something peculiar to Linux which I've overlooked. In any case, I'm putting these updated patches out in the hope of getting additional data back from anyone running perdition in daemon mode on Linux systems. Antonio Querubin whois: AQ7-ARIN

Domain delimiter question

by Urban Loesch

Hi, I'm using perdition as a POP3 and IMAP proxy for about 1 year. At this time I have 2 perdition servers as standalone proxies with one mailserver backend behind them. There was never a problem with this type of setup. Now I'm planing to split my mailserver backend in 2 ore more different servers. So I'm able to scaling out my server environment more flexible in the future. I'm trying to use mysql popmap for all of my hosted domains (about 6.000). My idea was to store all domains and the information of their backendservers in a mysql database. My database scheme looks like this: Domain Server Port domain1.com 192.168.1.10 NULL domain2.com 192.168.1.11 NULL domain3.com 192.168.1.10 NULL domain4.com 192.168.1.11 NULL ... and so on. With this setup I'm able to define for each domain a different backend server, which will be very practical for future scaling etc. The only problem I have is: All my users are using different logintypes. Some of them are using for example "user(a)domain1.com" as username. Other users are using "user%domain1.com" as username. So I have two different domain delimiters to search for (@ and %). To change this on the user site is not possible. There are about 25.000 users. I must find a way to filter the domain from the full username based on the domain delimiter. My current query key is: query_key \\d My map library options are: map_library_opt "mysqlserver:3306:dbname:dbtable:dbuser:dbpass:server:domain:port" Some of you have any idea how I can solve my problem? Is there a way to use 2 domain delimiters? Many thanks and regards Urban P.s. sorry for my poor english.
