We all miss something, every time.

  23 Telnet    # I'd block this in a heartbeat. Use SSH.

 113 Ident     # Optional, I block it and many people do

 137           #
 138           # Don't know names, but 137-139 are Samba
 139           #

 443           # Secure Web (HTTPS)

 587           # I don't know, but my server keeps telling
               # me that sendmail listens to 587

   1           # Don't know, but my server is listening on it
   6           # Don't know, but my server is listening on it
   7           # Don't know, but my server is listening on it
   9           # Don't know, but my server is listening on it

Anything else?
