[Dovecot] Problems with pam+ldap + quota
by Antonio Perez-Aranda 17 Mar '11

17 Mar '11

I think that I need to modify "/etc/ldap.conf" to remap some attribute with mailQuota from ldap, and then, try to catch this as arg. Someone has pam+ldap+quota ? -- Antonio Pérez-Aranda Alcaide aperezaranda(a)yaco.es Yaco Sistemas S.L. http://www.yaco.es/ C/ Rioja 5, 41001 Sevilla Teléfono +34 954 50 00 57 Fax +34 954 50 09 29

[Dovecot] exim and /var/run/dovecot/auth-client permissions
by John Connett 17 Mar '11

17 Mar '11

I am attempting to configure a dovecot 2.0 + exim + fetchmail (demon) combination on openSUSE 11.4, initially with the standard dovecot package (2.0.9-3.4-x86_64) and now with the later server:mail build service package (2.0.11-1.1-x86_64). I followed the instructions in http://wiki2.dovecot.org/HowTo/EximAndDovecotSASL but despite the changes in conf.d/10-master.conf the permissions on /var/run/dovecot/auth-client remain unchanged: $ ls -l /var/run/dovecot/auth-client Srw------- 1 root root 0 Mar 14 13:11 /var/run/dovecot/auth-client $ This is probably the cause of authentication failures from exim. I suspect it is something trivial but haven't yet been able to find the answer.

by Mark Adams 16 Mar '11

16 Mar '11

Hi all, Debian Lenny, dovecot 1.0.15 My rkhunter script has picked up dovecot using port 1984 temporarily. When I run it now however, it is gone. Warning: Network TCP port 1984 is being used by /usr/lib/dovecot/imap. Possible rootkit: Fuckit Rootkit Use the 'lsof -i' or 'netstat -an' command to check this. Does dovecot use this port for any reason? anyone seen this before? Regards, Mark

Hello, In a Dovecot 2.0.6 server I have an account x@domain and an alias y@domain -> x@domain. When I send an email to x@domain with carbon copy to y@domain, X receives two messages on mailbox. Dovecot2 has any feature of duplicate suppression ? Thanks, Thiago Henrique
