How does using smtps or vpn reduce abuse, if I
would be sending mail over my ISPs smtpd anyway?
And pointing to webmail doesn't really help
either. The question is whether you want to
offer _Internet_access or _web_access? Why not block
everything but Port 80? Abuse can be done with
ftp, ssh or netcat.

A million flies can't be wrong? I really hate
they even block ssh and I can't log into my
servers. If they offer Internet they should
deliver unfiltered IP. Next thing you know is they
block you from "harmful" websites, too.
