Trying to debug a delivery problem recently (with Postfix) and I realized that Dovecot wasn't logging any of the delivery information. I'm using Postfix to recieve mail, which is passing it on to Dovecot's deliver to actually deliver the emails into the mail boxes.

In dovecot.conf, I have: protocol lda { log_path = /var/tmp/dovecot-deliver.log }

[root]# dir /var/tmp/ total 2 drwxrwxrwt 2 root root 1024 Oct 22 12:30 . drwxr-xr-x 24 root root 1024 Aug 5 08:03 .. -rw------- 1 vmail vmail 0 Oct 22 12:11 dovecot-deliver.log

The log file gets created OK, but then stays at zero size.

Using: Postfix 2.3.3 Dovecot 1.1.4 (and previously 1.0.9)

Any clues as to how I can have a delivery log?
