RE: blocking email

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I assume you mean the email message is arriving at the intended mailbox as desired? If you mean something else, then please elaborate.

But if the information provided has helped you I think you could at least thank Robbin and Ace who worked so hard on this. In Robbin's case, he is contracted by Microsoft to help out here when he has free time from his regular job of performing like duties elsewhere. But for Ace, this is entirely voluntary. As for myself, my contribution was very small by comparison, and I would not be upset by your lack of appreciation, but I am embarrassed for this group that you show so little.

Hi Dave,

Thanks for you update.

Based on the current situation, if you can receive regular emails
from the vendor mail server except the automatically sent report
mail, then I agree with Larry and Ace that it is probably caused by
your Exchange server that may be the IMF or other 3rd party spam
filter block/reject the report email that from an automatic sent
email address(which might not exist and no mailbox at all) of the
vendor mail system.

Basically, to verify a legitimate sender, your Exchange server checks
for the sending domain's SPF (Sender Policy Framework) record, which
is published in the DNS record. The mail server then determines
whether the sending e-mail server's IP address matches the IP address
that is published in the DNS record. SenderID and SPF are not equal,
but enabling SenderID filtering will make your Exchange check
sender's SPF records.
