[TriLUG] issues with pop

[gregbrown at mindspring.com]

I'm sitting here in front of a RH 7.1 mail server that I've never 
seen in my life.  I know there is a pop server on this darn thing 
because that is how the mail clients are configured here and 
nmap tells me so but the pop server is something that I've never 
run across beacuse there is nothing in a 'rpm -qa' that looks 
remotly like a pop server.  I know there's an easy way to figure 
this out, but I'm somehow blinded.. could be the eight weeks of 
brain rot since Oculan went under. :)  Any ideas on how I can
easily indentify the pop server on this thing?
