I appologize again for being a Unix newbie and thank you for your patience.
In order of importance:

1. nmap reports that port 110 is not open, after considering it I just tried
"service popa3d start" and voila it now says started.  I reran nmap and there
it is, port 110 open.  So I go back to the client at it all now works.  I can
now breathe again.  Glad I had a Fedora box to run this from!  My t-bird is
on a Windows box.

2.  I guess it has to be manually started, as does postfix, if I reboot.  I
was fooled because I could go in as root and  enter popa3d    and it responds 
+OK   and then I can enter commands such as USER   etc.  So, I thought it
was started, obviously not.

3.  All of the documentation I have on this is the MAN output so - in effect
- I didn't realize how simple it was.  I didn't know to treat it as a service,
I just guessed; I suppose its obvious to everybody else but not me.

Thank you all again for all your help, this is a cute little piece of
software, I am so used to MS bloatware and I don't know how to deal with 
something this straightforward.
