The most accounts I have had with qpopper on one box is around 11,000. But
I am sure that I have had 160+ simultaneous connections several times --
well maybe not. I have had 160+ poppers all running at the same time, but
I do not think they all connected at the same time. (I can't remember
the machine's hardware. I think it was a pentium 200, 512MB ram and
SCSI drives.)
Anyways, you should just try to do 160 connections using some benchmark
programs or by making your own scripts to simulate this.
http://www.coker.com.au/postal/ may help. I have had heard of some other
pop3 benchmark tools. (I also made one, but I need to find it.)
As for authentication, consider using a password database (like BSD's
/etc/spwd.db) instead of a flat, text file (like /etc/shadow).
