Actually I'd like the option to prevent Xmail from returning all errors, especially 'user does not exist' ones (even if it's not an RFC thing). If its one of my local uses sending mail to an invalid address, I have no problem with them knowing about it via a 'warning email'. However, if it's someone external trying to send mail to an invalid user on one of our local domains, (especially if that email comes in via one of our secondary mail servers) I would much rather simply drop the connection, and return nothing at all. Numerous times we've had people spoof a return address and then send a stack of dictionary-attack-spam, to our domains (often arriving via the secondary servers, which are never used by our legitimate users to send external email). Since most uses do not exist, our server then bounces back a significant number of NDR's. If the spoofed return address is real, the person who owns the email account often thinks that we are spamming them (all the "error messages" returned by Xmail). This has gone far enough to get us blacklisted on some of the more radical lists, and our hosting provider to charge us for "spam-investigation incidents" - when it's been nothing but Xmail bouncing back (large numbers of) "cannot be delivered" error emails. If the sending address does not exist, stacks of NDR messages fill up Xmail's spool because they can't be delivered. So while I understand the reason for returning non-deliverable messages, it would be very helpful if Xmail at least had an option to turn off of ALL error returning. If this setting existed it would be very useful to use on our secondary mail servers.
