dovecot & postfix ssl (multiple subdomains for 1 server?)
 

I have a server that accepts and sends mail from mail.dept1.com and mail.dept2.com. the dept1 and dept2 can be used interchangably in the email address. It was working fine before, but I had to update the ssl certs. The ssl cert install only asks for 1 CN, so if I log on with the other dept, it get the error that it I have attempted to connect to mail.dept1.com when the cert belongs to mail.dept2.com.

How can I fix my certs?
