AOL blocking MailScanner messages!

[Mike Kercher]

See, I have a bigger problem with discarding mail based on incorrect RDNS.
I'd rather reject the message so that HOPEFULLY, someone can fix the
problem.  If the emails are accepted by your MTA and then discarded, the
sender assumes that his/her email was delivered successfully.
