My question is it good practice these days to have a system bounce the mail or drop the mail seeing that it's possible that the bounce mail is being sent from a spammer. Doesn't this just notify the spammer(s) that this is a valid server running, just the name is not accepted. Or is there a better way of handling this?
spam is generally sent with a forged sender address. bouncing it results
in backscatter. see the backscatter readme.
Try to reject instead of bounce. in particular, implement recipient
validation correctly. Also, don't configure your spam filter to bounce.
tag and deliver or quarantine.
