Quote: Why any ISP of any kind that lets port 25 traffic go outbound is beyond me.
I work for an ISP, and I've been trying to convince the other sys admins of that for a while now. It might be okay to leave outbound port 25 for static IP accounts since they often have mail servers on their connections but for dynamic IPs...nah--outbound port 25 causes far too many problems. Not enough people use dynamic DNS for outbound port 25 to be anything more than 1) spam zombies or 2) bonafide spammers. In either case, you don't want them sending from your network.
