  I believe that it would look like this.

access-list 101 permit tcp any host 255.255.255.255 eq 25
access-list 101 permit tcp any host 255.255.255.255 eq 80


  This would permit tcp packets from any host to go to port 25 and 
port 80 of machine 255.255.255.255.  Everything else is denied 
implicitly(sp?).  You would then apply it as a inbound filter on you 
incoming port.
