Accepted Domain - Recipient address rejected: Access denied 554 5.7.1 - Exchange 2007

Migrated from SBS 2003 to SBS 2007 and changed the internal domain name. SBS 2003 was receiving e-mails for domain1.com and domain2.com

Migration went well, exchange is up and running and functioning for domain2.com but I cannot get e-mails to be received on domain1.com

We are using Trend Micro Hosted E-mail and getting an NDR sent back:

in11.sjc.mx.trendmicro.com #554 5.7.1 <user@domain1.com>: Recipient address rejected: Access denied ##

I have added domain2.com as an accepted domain.
I have adjusted email policy to add this an smtp address, and confirmed it was added to the mailbox user
I have added the IP address range for Trend on the receive connector to allow e-mail to be received.
I have selected "anonymous users" for the permission groups on receive connector.
I have selected TLS and basic authentication on receive connector.
I have allowed the remote IP address on the anti-spam tab. (I even disabled and tested)

Any ideas what I'm missing?

They are rejecting you because you are a dynamic IP user.

You may be able to request that your ISP create a proper PTR (or reverse DNS entry) for you, but I think the better option will be to use an SMTP connector and your ISPs mailserver as a smarthost - as described here -> http://www.amset.info/exchange/smtp-connector.asp

This is exchange 2007. ISPs mailserver was setup as a smarthost, followed the SBS Wizard for this.

Emails is fine for domain2.com but not domain1.com.

Nothing changed except for the exchange server - all mx records are pointing to the same place, same trend micro. I think it's because there's a configuration in exchange that is missing to allow e-mail to come in for domain2.com.

when i try to send internally from domain1.com to domain2.com i get:

Diagnostic information for administrators:

Looks like this is being caused by spam filtering.
