There have been no changes to the Exchange Server 2003 portion of SBS 2003 and now this morning our clients can't send mail to us and receive the following message.  We were able to receive mail on Friday but not by Monday morning.  The server has been rebooted and there are no erros in the event log.  What could have happened?


The following recipient(s) could not be reached:

      swalsh@burgessharrell.com on 6/26/2006 1:26 PM
            You do not have permission to send to this recipient.  For assistance, contact your system administrator.

Is your server set to relay through an external smarthost?
If so they may have changed their relaying policy.

Goto:
Server Management
Advanced Management
Exchange
Connectors

Right Click Small Business SMTP Connector and select properties
It will either be set to use DNS or a Smarthost

It's set to use DNS.  The DSL service provider is Verizon.

Verizon have become very strict with regards hosting servers on their non-business dsl lines.
Do you have a Business DSL Line with them?

I saw a post yesterday on Vlad Mazek's blog about Verizon stopping access on ports 80 and 443 to some customers, as the post was based on web access, it may not have covered a change in policy for port 25.

Thanks, Verizon did migrate them to a new server and I got no notification that the MX and mail records needed to be changed.
