Re: Spam relaying problem NOT fixed

Thanks for replying.  This is exactly what we did this past Thursday.  It
appeared to work great, however some emails were being bounced back to the
sender with a message like:  "Server Error: 554; SMTP message rejected for
policy reasons."  Not all messages were rejected, only some.  This is why
I'm so confused as to what to put in the "Allow / Deny" fields.  I don't
understand why some messages would be allowed and others be rejected.

Thanks for taking the time to respond,
