Pop3 Stopped Working On Red Hat 8 System

[Richard Wells]

Hello list,

Bill Acker had configured pop3 to work on my Red Hat system. I can still 
telnet to port 110 from inside and do mail commands, but I cannot get to 
it from outside at all. Did my ISP do something or do I need to change 
something or maybe even restart pop3? All ideas/command examples are 
welcome. I would really like to be able to hit pop3 remotely again.

Thanks inadvance.
