I have done it in the past and i can tell you filtering outgoing mail for spam is just a bad idea Try googling then. You will find most anti-spam orgs moan about ISPs/ESPs NOT doing it. If M$,Yahoo,Gmail etc filtered their outgoing, the work of anti-spammers would be a lot easier. In theory, for most "normal" non bulk mail customers, filtering outgoing should be very low overhead compared to the incoming but would hit hard on spammers using hijacked user accounts. Because some spammers send only a few spams per user account, relying on volume only as an incator is becoming less reliable as time goes on. All the best Phil It's mostly to detect and block if people have been hacked or if they have someone show up with a virus that get's their IP blacklisted it won't matter because I'm the one sending their email. I can do a lot of sanity checks that they probable won't do themselves. I basically have something working now and going to look for people who want to test it.
