We have SBS 2003 with Exchange. I have set up mail forwarding for certain users so that any mail received in their Inbox gets forwarded to their blackberry. To do this, I create an AD User Contact with the users' blackberry address, and have Exchange forward mail to that address.

This works fine, except for certain cases, usually when the sender is also using a blackberry. The mail gets received in Exchange (and the users Inbox), but it is not forwarded to the users blackberry; instead, the sender gets "Delivery Status Notification (Failure)" with an attachment that contains:
Final-Recipient: rfc822;user@att.blackberry.net
Action: failed
Status: 5.7.1
Diagnostic-Code: smtp;550 5.7.1 Client host rejected:

There is also a link, which resolves to openspf.org which says:
rejected a message that claimed an envelope sender address of sender@senderdomain.com.

received a message from ExchangeIP that claimed an envelope sender address of sender@senderdomain.com.

However, the domain senderdomain.com has declared using SPF that it does not send mail through ExchangeIP. That is why the message was rejected.

I'm at a loss on how to proceed in troubleshooting/fixing this problem. I ran across this thread thread955-1415554, but no resolution there.

Any ideas?

Thanks for the reply.

Yes, we have OWA set up.

We have an ISP that does smarthosting... mail.ourdomain.com resolves to the ISP's mail server, and that mail gets forwarded to mail2.ourdomain.com, which is the Exchange Server.

Is BIS going to work in this situation? When I went to BIS for Verizon, and click "Set Up Account", it asks me for email address and password, not mail server.

I believe you would put username@yourdomain.com and them your OWA password

It is detecting the email originated from their system, then passed through yours and cam back to them to be resolved for another user. Their filters are probably that good.

With our setup I have 5 blackberry users and I downloaded the free Blackberry Professional Server which can handle up to 15 users, and like I said its free instead of spending thousands for the enterprise edition. Then I just set it up on the exchange server and tied the blackberry users in and now all their email, contacts, calender and tasks are syncronized with the exchange server.

Thanks for that, reynolwi.

I think I'm going to try TechyMcSe2k's suggestion first, as we already have OWA... might end up being a simple replacement to the forwarding we're doing now.

But the Blackberry Professional Server looks good also... Never knew about it, thought Enterprise was the only alternative like that.

reynolwi ...

The link gives you the software plus 1 users license.

How did you get additional user licenses for free?

Thanks

For every user I had I did the same process you did to get the one license just used that users information and Blackberry PIN
