External Email not being recieved by Exchange 2010: Issue with SMTP Receive Connector RRS feed

  • Question

  • On our CAS0 box, we are getting the Event:

    Microsoft Exchange could not find a certificate that contains the domain name mail.domainname.com (actual name not published) in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Internet Relay with a FQDN parameter of mail.domainname.com. If the connector's FQDN is not specified, the computer's FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key.

    We have recreated the Internet Relay Receive Connectors on the Servers/HubTransport.

    We host multiple mailbox (1,000) for multiple companies, and we have a mixed Exchange 2007 and Exchange 2010 Server environment.

    Any assistance would be greatly appreciated,

    Thank you,

  • Watch out for the help file as it will be updated soon, http://technet.microsoft.com/en-us/library/ff952753.aspx.

    In the meanwhile, also have a look at here, http://blogs.technet.com/b/provtest/archive/2010/07/27/exchange-server-2010-sp1-beta-hosting-deployment-part-7-transport-segregation.aspx to understand the mail flow in Hosting deployment. 

    Hosting deployment needs to be in the brand new forest, can't be deployed on existing E2k7 box.

    Now the error indicates that the certificate is not configured properly if you are configuring TLS. If you are using TLS, you need to get the cert with the right name.
