To stop the % hack , aka "sender routing", completely (independent of the yes/no morass), we put that one regex in the file and it catches errors like this, as well as % junk:
reject: RCPT from roc-smtp3-sun.choiceone.net[64.179.30.54]: 550 <[EMAIL PROTECTED];[EMAIL PROTECTED];[EMAIL PROTECTED];[EMAIL PROTECTED];d [EMAIL PROTECTED]>: Recipient address rejected: Sender-specified routing rejected; from=<[EMAIL PROTECTED]> to=<[EMAIL PROTECTED];[EMAIL PROTECTED];[EMAIL PROTECTED];[EMAIL PROTECTED];[EMAIL PROTECTED]> proto=SMTP helo=<roc-smtp3-sun.choiceone.net> ... which is ;-delimited recipients instead of comma- Len
