Hello,

I am running dovecot-2.0.13-1_128.el5 x86_64 RPM on CentOS 5.7 with the config shown below.

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: 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)

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 anvil srw------- 1 root root 0 Dec 9 21:27 anvil-auth-penalty srw------- 1 root root 0 Dec 9 21:27 auth-client srw------- 1 dovecot root 0 Dec 9 21:27 auth-login srw-rw---- 1 vmail vmail 0 Dec 9 21:27 auth-master srw------- 1 root root 0 Dec 9 21:27 auth-userdb srw------- 1 dovecot root 0 Dec 9 21:27 auth-worker srw------- 1 root root 0 Dec 9 21:27 config srw------- 1 root root 0 Dec 9 21:27 dict srw------- 1 root root 0 Dec 9 21:27 director-admin srw-rw-rw- 1 root root 0 Dec 9 21:27 dns-client srw------- 1 root root 0 Dec 9 21:27 doveadm-server lrwxrwxrwx 1 root root 25 Dec 9 21:27 dovecot.conf -> /etc/dovecot/dovecot.conf 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).

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?

Please advise.

Thanks in advance, Nick
