[Mailmunge] Logging

I noticed the "because filter instructed us to" messages in mailmunge.c 
are all LOG_DEBUG. Is there a way to tell mailmunge in config to only 
log INFO and higher? Or would i have to do that in rsyslog on all 
messages to the mail facility? Id rather not get into hack and slashing 
the C code if possible.
