> Hi all,
>
> Today my mail server -
> fedora/sendmail/mailscanner/sa/mailwatch has approx 3000 non
> legitimate emails to one of the domains I scan and relay to
> Exchange 2003. All these emails have no from address and the
> subject varies from a)**Message you sent blocked by our bulk
> email filter** and b)Mail System Error - Returned Mail
>
> Is there a way to stop this?
>
> I scan and fwd mails for many domain.
> Maybe there is a way that somewhere I can set - these are the
> only email addresses I want to accept email for , for a
> particulare domain, and drop all other email. Then MS Can
> only receive genuine email addresses? This maybe is not the
> best solution as if the exchange admin adds new accounts he
> would have to notify us of the new addresses...
>
> Any help or pointers would be greatly received
>
