Cannot send but can receive email : os x 10.4 POP port 110; internet browser access OK; Mail connection doctor says "Mail unable connect to internet"; green dots for mail account names "connection and login to server succeeded";

red dot for smtp.comcast.net "could not connect to SMTP server".      Account preferences appear same as on another computer in which mail is OK.  


This message could not be delivered and will remain in your Outbox until it can be delivered.

The server "smtp.comcast.net" cannot be contacted on port 25.


Network Utility Port scan on 25 and on 110 OK. Have not found blocking by firewall.

Also, Why port 25 in one error message and not in other error message when I see port 110 in POP account setup?
