Subject: SMTP after POP3/IMAP
I have run into a problem setting up a script to allow SMTP access to my
server after a POP3/IMAP connection. The problem is I use stunnel to
provide secure (relatively) POP3S and IMAPS connections. This
effectively breaks the logging mechanisms of Cyrus mail system by only
recording the local ip (127.0.0.1) when a user connects. As a result
the POPwatch script only adds 127.0.0.1 to the SMTP relay access list.

I've tried to link the Stunnel and Cyrus logging information, but they
do not have any commonalties in the logs that can link a username to an
IP address. Anyone have any other ideas?
