Thanks for everyone who responded to this. As for the topic of rejecting bounces, while I agree the RFC was written in a kindler gentler time, I don't think that rejecting bounces is a good idea.
Please correct me if I'm wrong, but my understanding runs like this: Bounce a message, and your mail server creates a new bounce message and sends back to the sender of the suspected spam. Reject a message, and if the sending system is a genuine mail server, /that server/ will send an error message to the local user regarding the "bounce." If the sending system is a suborned spammer, the reject will be ignored and it will pass on to the next address in the queue. Result: genuine users do receive word of the delivery failure; forged sender addresses go unmolested. -- Regards, -- Cal Frye, Network Administrator, Oberlin College www.calfrye.com, www.pitalabs.com "The louder he talked of his honor, the faster we counted our spoons." -- Ralph Waldo Emerson.
