[about outbound filtering]

This is going to become a lot more common for a couple of reasons:

1) As ISPs block outbound port 25 connections, spam zombies are going
to use the ISPs relay to send outbound spam.  This will force ISPs
to filter outgoing mail, or risk getting blocked as spam sources.

2) All kinds of regulations in the US like HIPAA and financial
regulations will force businesses to at least pretend to control
outflowing information.  Unfortunately, doing this effectively means
prohibiting tools like PGP for encrypted e-mail. :-(
