[Dovecot] "doveadm log reopen" don't reopen separate lmtp log

[Timo Sirainen]

The problem isn't lmtp itself, it's that you're using -L parameter, which causes LMTP processes to open the log files directly. The only way to reopen the log files is to restart those LMTP processes. "doveadm reload" should do it.

After some time, usually a few minutes, logs are being written to this file anyway. But if I compare this to my maillog, it misses some deliveries just after the log rotation.
