[Dovecot] defunct in 1.24 on FreeBSD Alphaserver
by Paweł Kaczor 05 Nov '09

05 Nov '09

Hello, I've recently upgraded Dovecot from 1.1.16 to 1.2.4 on FreeSBD 6.3- RELEASE running on old Alphaserver 1200. Some time after this upgrade all user's MUAs showed error that user password was not accepted. I've noticed many zombies of imap and pop3 processes on my server (all in defunct state). Looks like when "login_max_processes_count" was reached, Dovecot canceled all new connections. I've setup completely new configuration based on http://wiki.dovecot.org/TestInstallation and no error was produced but every time I closed telnet the imap process became defunct. So, I tried to trace what was happening with ktrace: ktrace -d -f log -p pid_of_imap_process In attached file is a part of ktrace output at the moment when I close telnet connection. What is interesting (at last for me, but I'm lamer) is an error: 1576 imap 1256902587.568406 CALL close(0xffffffffffffffff) 1576 imap 1256902587.568448 RET close -1 errno 9 Bad file descriptor AFAIK, such error could be produced by inconsistent file system so I double checked OS and I'm 100% sure it's OK. At the very end of this history I had to switch back to 1.1.16 version of Dovecot which works OK now. I'll be very thankful if somebody could point me to explanation what can cause such strange behavior. Regards, Pawel Kaczor -- "A z kwiatków, jakie pan lubi najbardziej?

[Dovecot] IMAP goes down from time to time
by Juan Felipe Estrada 05 Nov '09

05 Nov '09

Good Morning I´m writing back cause the IMAP going down issue has changed a little, i still have the dovecot-1.0.7-7.el5 but with 2 changes; I added to the dovecot.conf the outlook-idle workaround, and the three login_processes parameters login_process_per_connection = yes login_processes_count = 3 login_max_processes_count = 128 Since I added this parameters the IMAP process has gone down just 1 time in 2 weeks, before this, the proccess was going down about 4 times a day so I think this is suitable, the next step i´ll take is to update the Dovecot.

[Dovecot] Why : dovecot_destination_recipient_limit = 1 ?
by Koenraad Lelong 03 Nov '09

03 Nov '09

Hi all, I'm trying to activate sieve. In all tutorials I have seen I need to set dovecot_destination_recipient_limit = 1 in Postfix's main.cf. Can anyone explain why ? I like to know because when I set this and the dovecot transport in Postfix, I'm having problems when aliasses are used that map to different recipients, i.e. info@... results in user1@..., user2@..., etc. The problems are an error from Postfix : Oct 30 09:25:19 lace3 postfix/pipe[19729]: 8A77E2D5B5B: to=<some.body(a)some.where.org>, relay=dovecot, delay=2390, delays=2390/0.04/0/0.01, dsn=4.3.5, status=deferred (mail system configuration error) Oct 30 09:25:19 lace3 postfix/pipe[19729]: warning: pipe flag `D' requires dovecot_destination_recipient_limit = 1 Thanks for any info. Regards, Koenraad Lelong.

[Dovecot] X.509 certificate based IMAP login
by dovecotlist＠encambio.com 03 Nov '09

03 Nov '09

Hello list, The dovecot version is 1.2.6 running on Solaris x86 11 (nv-b91). The relevant configuration lines are: passdb ldap { # LDAP database (doc/wiki/AuthDatabase.LDAP.txt.) args = /pfx/etc/dovecot/dovecot-ldap.conf } The file dovecot-ldap.conf is correct and LDAP authentication is working well. We would like to make it possible for users with a X.509 client certificate to log in without providing LDAP or any other credentials. Is there something like: passdb x509 { args = /pfx/etc/dovecot/dovecot-caroots.pem nopwd = yes } ...avaibable, or is there another solution? Thanks, Brian
