I receive this error on event viewer:
Microsoft Exchange couldn't find a certificate that contains the domain name srvmail.mydomain.com in the personal store on the local computer. Therefore, it is unable to offer the STARTTLS SMTP verb for any connector with a FQDN parameter of srvmail.mydomain.com. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for every connector FQDN.
I think the only certificate i have was created with the installation of exchange 2007 for srvmail.mydomain.local. Can anyone explain how resolve this error? I supouse that i have to install a local CA and then create a new certificate, but how i install this on exchange 2007 connector?
