I noticed the FQDN listed on our SendConnector (the one sent in response to helo and ehlo requests)is configured as mail.mydomain.com and the certificate reads remote.mydomain.com. I have some Event Log errors and I'm sure this is messing up some outgoing email. My question is, would it be easier to change the FQDN that is listed on the SendConnector or create a new certificate? If I change the FQDN will I have to change the MX record at the domain host as well? I have mutiliple domains sending and receiving on this Exchange server. How will this affect those domains?
