I'm sorry, this is not correct.  The firewall preferences determine 
allowances for INBOUND connections on a port.  The response from an 
external POP server will be directed to the port of whichever random 
number above 1023 the Mac used in its connection attempt, not port 110. 
  It will be SOURCED from port 110.

Same issue.

Quite likely.  One debugging step is to attempt a telnet connection 
from the Mac to port 110 of the mail server.  If it succeeds, the 
problem is with Mail.app.  If it fails, the problem is elsewhere 
(network or destination server).
