Besides architectural purity (which still bears weight) the
problem is that configuration costs money. I have my own SMTP
server at home because I'm not happy with my ISP's smarthost.

That same ISP can't reverse-lookup my static IP to return a PTR
that has my domain name in it, explain me how they will build a
filter that un-filters port 25 for my IP and does not for the
next one.
