Re: [Dovecot] too many open files and v1.2
Hi Timo thanks for your reply. I understand you're basically saying "upgrade to v2" but maybe this could be of interest for you. After we lowered the login_max_processes_count again the problem reappeared so I'm not sure whether that doesn't indicate a different problem.

[Dovecot] too many open files and v1.2
Hi I've found an older thread http://www.dovecot.org/list/dovecot/2010-March/047886.html which mentions that this is a bug in version 1. I'm on Debian squeeze (1:1.2.15-7) and got errors like these recently Oct 5 11:29:29 mail dovecot: dovecot: pipe() failed: Too many open files Oct 5 11:29:32 mail dovecot: dovecot: pipe() failed: Too many open files Oct 5 11:29:32 mail dovecot: dovecot: Temporary failure in creating login processes, slowing down for now As a work around I've increased login_max_processes_count from 256 to 512 and it seems to have helped (as I suspected stale opened files). My colleague thinks it's hitting the kernel open file limit ulimit -n (currently at 1024) but I don't see how that could happen if the number of process is nowhere near that. Any ideas? Thanks, Michael
Re: [Dovecot] drac plugin "net_ip2addr() failed: Operation not permitted"
Anybody? I know using pop before smtp is antiquated but we have a legacy/sustainability issue.. mimo On Monday 11 July 2011 13:05:02 Michael Moritz wrote: > Hi, I'm trying to get the drac plugin working (again) but I'm stuck with the > following message: > > Restarting IMAP/POP3 mail server: dovecotEDRAC: net_ip2addr() failed: > Operation not permitted > > This is on a Debian Squeeze box, dovecot version 1.2.15-7, drac version 1.12 > > Looking at the source it should print the IP in the brackets of net_ip2addr. > The fact that it's just empty made me think that I may need to set an > environment variable.

[Dovecot] drac plugin "net_ip2addr() failed: Operation not permitted"
Hi, I'm trying to get the drac plugin working (again) but I'm stuck with the following message: Restarting IMAP/POP3 mail server: dovecotEDRAC: net_ip2addr() failed: Operation not permitted This is on a Debian Squeeze box, dovecot version 1.2.15-7, drac version 1.12 Looking at the source it should print the IP in the brackets of net_ip2addr. The fact that it's just empty made me think that I may need to set an environment variable. I tried IP="127.0.0.1" in /etc/default/dovecot and as export but to no avail. Any ideas? Thanks, mimo

[Dovecot] postfix + dovecot lda,
I'm trying to replace procmail with deliver but I'm having problems with the group part of things. I keep getting: Aug 29 16:44:19 dingbat deliver(mimo): open(/var/mail/.temp.dingbat.3969.d1689935a308e0dd) failed: Permission denied Aug 29 16:44:19 dingbat deliver(mimo): file_lock_dotlock() failed with mbox file /var/mail/mimo: Permission denied My primary group is mimo and I think it's trying to use that. I changed it to mail and things work. But I do not want all my users to have a primary group mail. Is there a way I can force deliver to use group mail as group and ignore the per user gid? I tried chmod 6755 /usr/lib/dovecot/deliver but no change. This is on debian/etch, help appreciated mimo
