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

Perdition + imap (maildrop doesn't send bounce back messages.

by Gejo Paul

Dear All, I am using perdition + courier + postfix+ ldap+ maildir (mail quota) on my mail servers. All the functions are working fine on the server except one small issue. I configured mail quota on the mail servers, suppose if the user quota becomes full condition 1 if the sender mailbox and receiver mailbox existing on the same mail server the sender get a bounce back message that user quota is full. if the sender and receiver mailbox existing on two different machines , it doesn't bounce back any messages.bcoz the receiver home directory is not existing on the same server ERROR LOG relay=maildrop, delay=0, status=deferred (temporary failure. Command output: /usr/local/bin/maildrop: Unable to change to home directory. I am looking for a breakthrough to tackle this issue Any ideas and suggestions are welcome Best regards Paul

perdition and ldaps

by Graham Leggett

Hi all, I tried to enable ldaps on my connection from perdition to my LDAP server (which currently supports both ldap and ldaps), and it causes connection attempts to IMAP to silently fail. In theory, at the very least a CA certificate needs to be specified before ldaps can work, and I have not found anything in any documentation or command line option to suggest this is possible. I did find a reference to a commit back in 2004 claiming that ldaps URLs were then supported, but this didn't seem to have been documented anywhere. Does anyone know what the status is of either ldaps or ldap+starttls? Regards, Graham --

Perdition IMAP and Webmail IMP/Horde

by LEVEAU Stanislas

I use perdition IMAP proxy with webmail IMP/HORDE. It out-going to a store SUN messaging server. When I display more then 100messages with webmail is very slow with perdition. With an other IMAP proxy it's fast. Is it possible tuning Perdition? my current configuration is simple /etc/perdition/perdition.conf M /usr/lib/libperditiondb_ldap.so m "ldap://ldap.domain.fr:389/o=domain,c=fr?uid,mailhost,port?sub?(uid=%s)" regards Stan

Switching from Mailhost to Mailhost

by Sergej Popanov

Hi! As far as I read documentation the following is not possible but please correct me if I am wrong. I want to migrate users from one mailhost to another. The accounts have this syntax: postbox[1-9]{1,3} On the new mailhost users have that syntax: username(a)domain.tld The plan is to use a proxy that can translate $postbox -> newaddress(a)domain.tld. My first thought was that I can use postmap for that, but as far as I read docu there is no possibility to add the other account to the hostfield. If it is possible please give me some advice, if it is not possible a pointer to another mailproxy software that supports that would be gladly appreciated. Cheers Sergej

POP always timeout but IMAP is always OK

by Nelson Serafica

Hi to all, I have perdition running for so many years now. I got this problem just this morning. There are several calls all is using pop3 authentication. According to them, error is pop3 is not responding. But the thing is, they can telnet the port and login via msdos prompt successfully. However, if they are using email client, mostly it was timeout. I got this in my perdition log. Jul 11 16:56:37 perdition[29356]: Fatal error piping data. Exiting child Jul 11 16:50:06 perdition[27111]: token_read: token_fill_buffer Jul 11 16:50:06 perdition[27111]: read_line: token_read Jul 11 16:50:06 perdition[27111]: pop3_out_response: read_line Jul 11 16:50:06 perdition[27111]: quit: out_response Is there a need to change in my perdition.pop3.conf? I enable debug to see any error but only the thing above is the most related to the problem. Please note that there is no problem in IMAP. Find out exchange rates - Yahoo!
