We do both...but I wouldn't say whitelist like crazy. More like whitelist as needed, and find a blacklist or one of the message body parsing utils you like...or both. For the rare emergency when a customer (or non-customer) needs to talk to our NOC and can't get email through, we have these neat things called telephones. They work pretty well. In fact, I think mine often works too well. -- ---------------------------------------------------------------------- Jon Lewis *jlewis () lewis org*| I route System Administrator | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
