[Dovecot] Quota warnings not being sent

[Nikolaos Milas]

Hello,




All accounts are virtual, hosted on LDAP Server.

My problem is that the quota warning mail is not sent as expected.

For example, in the logs I get:


Here is /var/run/dovecot/:

# ls -la /var/run/dovecot/
total 32
drwxr-xr-x  4 root    dovecot  4096 Dec  9 21:27 .
drwxr-xr-x 23 root    root     4096 Dec 14 12:27 ..

srw-------  1 root    root        0 Dec  9 21:27 doveadm-server

drwxr-xr-x  2 root    root     4096 May 17  2011 empty
drwxr-x---  2 root    dovenull 4096 Dec  9 21:27 login
-rw-------  1 root    root        5 Dec  9 21:27 master.pid
srw-------  1 root    root        0 Dec  9 21:27 quota-warning

Follows my config (at the end of this message).



Please advise.

Thanks in advance,
Nick

I am running dovecot-2.0.13-1_128.el5 x86_64 RPM on CentOS 5.7 with the config shown below. Dec 12 08:42:40 vmail dovecot: lda(imaptester): Error: quota: net_connect_unix(/var/run/dovecot/quota-warning) failed: Permission denied (euid=500(vmail) egid=500(vmail) missing +r perm: /var/run/dovecot/quota-warning, euid is not dir owner) lrwxrwxrwx 1 root root 25 Dec 9 21:27 dovecot.conf -> /etc/dovecot/dovecot.conf How should I change permissions to resolve the issue? Would it be enough to change ownership of the whole directory /var/run/dovecot/ and its contents to vmail:vmail? What configuration directives determine the ownership and the access permissions for these sockets?
