Kind of off topic and bear with me I'm not real familiar with certs. Exchange 2007 sp2/Ironport perimeter. We recently added new certificates to our systems. Some of our affiliates have established TLS connectors to our site for mandatory encryption between our sites. The remote site in question is running Exchange 2010 but when they try and send mail to our uc.edu domain name, all the messages get spooled. If they send to ucmail.uc.edu the mail goes through fine. The error they getting for the uc.edu domain is a 451 4.4.0 Primary target IP address responded with "44.4.7.5 Certificate validation failure". Uc.edu is our university wide domain name so I'm a little confused on how that comes into play with the TLS connectivity and mx/a records. Here is another error reported.
A secure connection to domain-secured domain 'uc.edu' on connector 'UC TLS Connector' could not be established because the validation of the Transport Layer Security (TLS) certificate for uc.edu failed with status 'UntrustedRoot. Contact the administrator of uc.edu to resolve the problem, or remove the domain from the domain-secured list.
