[Dovecot] LMTP logging configuration

Hi,

I'm using Dovecot 2.0.1, and I log to a custom syslog facility (local0) in the
main configuration (I want a separate log file, but I want to make use of rsyslogd's capabilities). I overwrite the syslog facility for LDA (mail) to have all delivery related stuff in /var/log/mail.log, and that works fine.

I tried to do the same for LMTP with protocol lmtp { syslog_facility = mail }

but this has no effect, LMTP logs to local0. Is this supposed to work, or is this not implemented at all? If not, is using a logfile in main config, but syslog in lmtp supported?

Thanks Rainer
