Hellowe had a problem with a Virus scanner not forwardig a mail with a sender address including two "@" characters. The mail was accepted by Postfix and the problem is we don't want to bounce or drop anything after Postfix has accepted it. The AV vendor claim that RFC 5322 would not allow such addresses but i wonder how to reject something like "address@@domain" or if this is even recommended.
