That was 50,221 users on one dual processor (PIII 3.02Ghz Xeon) dell 
2650 with 4gigs of ram. I'm not sure about concurrent users, but we have 
as many as 10 to 15 authenticated connections per second.

This mail server hosted just over 12,000 virtual domains.... handles 
thoasands of messages per hour.  postfix is running on the same 
system.   Its running beautifully too...  I've converted over three more 
systems with almost identical environments...
