Logging SMTPD ports

[Robert Sharp]

Hi

I have postfix set up with smtpd processes on three ports: 25 for the 
wild world out there, 587 for submission from local users and other MTAs 
on the LAN, and 10025 for re-injection from amavis. I am doing some log 
analysis and I think it would be really, really helpful if smtpd could 
log its port. That way I can easily distinguish between message threads 
without trying second passes based on message or queue IDs. I would 
imagine it is a fairly easy thing to implement? Can it be done through 
some setting somewhere that I have not yet found?
