Everyone's solutions have been pretty interesting[1]. I'm surprised (although, yes, I knew) that there aren't less sysadmin-y solutions: blocking outgoing SMTP is getting pretty common.
Networks *should* block outgoing SMTP from anything but authorised mail servers. They should, however, allow IMAPS (993) and Authenticated SMTP (587 to allow users to exchange mail with third-party servers. In this day and age mail servers shouldn't relay unauthenticated mail from within a network to the outside. That's just asking for one infected PC to drop the entire domain into a spam blacklist. -- Glen Turner -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
