Black Spam and Yahoo Messenger

By PowerIon2 ·
I am looking for a good/economical solution for blocking spam on workgroup mail. Additionally I am trying to find the port that Yahoo Messenger uses so I might be able to get an ACL in place on the cisco router. Thanks ahead for any replies.

Yahoo uses port 5050 i'm sure but if you ever want to find out what port a piece of software uses etc. run the application and then simply do a netstat -a from the Dos promt.

You forgot to say wether your workgroup mail was Pop3 or SmTP.
