tcpserver - pop3d logging

[Kurth Bemis]

i know that its been asked on the list before.....but i can't remember when 
or the answer for that matter.

i'd like to log the usernames from my pop users...to see who is getting 
their mail and whose not :-)

i thought that there was a tcpserver or multilog switch for it...but i 
can't remember...can someone help me out :-)
