Blocking port 25 outbound is one of the most effective methods of limiting direct spamming from dialups. For every Linux user who can maintain a reasonably secure mail server there are probably 100,000 clueless Windows users (but I repeate myself) who have no legitimate reason to send to any server other than their ISP's. We generally set up our customer who're running on cable connections to send/receive their e-mail through our servers using uucp over tcp/ip which sidesteps all these problems, and eliminates their dependency on the cable provider's mail sysetm.
