[Courier-imap] PATCH: Log source port.

[Adam Hasselbalch Hansen]

Enclosed is a patch that makes imapd log originating port number in 
addition to ip.

This is due to new legislation in Denmark, requiring ISPs and hosting 
companies to log the originating port of all traffic.

This has been successfully applied to 0.53.3 and 0.56.0.
