IMAP, POP3, FC1 vs FC3

[poohba at blkpoohba.dyndns.org]

I know that FC3 uses a different program but I want to use what I had 
working in FC1.  Which pop and imap server did FC1 use?  I would just 
stick with what FC3 has but I can't get pop or imap and its frustrating 
me.  I'm glad I can ssh in and get my mail via pine but I want to be able 
to get it from anywhere with pop.  Which servers do I need to download so 
I can get back to my old FC1 config w/o actually going back to FC1?
