Re: [Dovecot] Dovecot Deliver Problem

Sep 12 23:17:30 server deliver: net_connect(/var/Process/dovecot/auth-master.socket) failed: Connection refused

AFAIK, this usually means that there is no process listening on that socket.

    master { path        = /var/Process/dovecot/auth-master.socket
             mode        = 666

This is not sufficient, as dovecot will set the permissions of /var/Process/dovecot/ to 700 (given that this is your login_dir). So I put the socket into /var/spool/vmail, where the user that runs the lda has sufficient rights.
