But the mail is not being bounced but tagged as spam in MS. If the RBL
checks are set in MailScanner then messages from that IP address will
always be marked as spam. Better still as Martin suggested is to remove
all RBLs from MailScanner and let SpamAssassin check them. This won't mean
that there isn't a chance that the message is tagged but it's less likely.
