Betr.: Re: Mailscanner performance monitoring ?

[Jerry Benton]

This is correct:

"As far as I know, by default Exchange servers wil accapt all addresses for
their domain so they can bounce a nice cryptic message back to the sender."

There is a video on the Mailborder site covering recipient verification. It
walks you through how to setup Exchange. The MailScanner portion is Postfix
based, but the Exchange part should be useful to you.
