<rant> I wish that my Outlook Express 6.00.2800.1123 client would *always* prefix the sender's original message with ">" as I configued it to do but it only does so for certain e-mails that I reply to. No idea how to fix this. Hints anyone? </rant>

There are a lot of real email-recipients, but also some containing only special characters." I'm assuming a typo here because if this "user" managed to [re]configure your SMTP server, you have bigger problems than strange characters ;) And when you say "user", do you mean one of your own customers? I don't see SMTP AUTH as being in the picture here -- please correct me someone -- unless the sender is indeed one of your customers but not a local user. If so, s/he would indeed have to AUTH against your server and you would see log lines saying "session treated as local" in your SMTP logs. "The sender-adress is even "<>"." This is perfectly legal (and was part of the telnet test I suggested that you run -- please see below). Accepting messages from null (<>) senders is mandated by the RFCs and is the way bounce messages are delivered. (Yes, a relatively small number of spammers use this as they know/expect that the target mail server will accept their junk, but refusing null senders is in violation of the RFCs, not to mention that it will irritate other mail server admins and get you listed in http://www.rfc-ignorant.com. (Please see the archives for this topic.) "Looks like this guy has an email worm on his computer..." It could be. I'm still interested in knowing what you get if you run the test I described below.
