[Dovecot] Two server certificates for two common names

Hi there!

I have two DNS records mail1.domain.tld mail2.domain.tld

I have issued SSL server Certificates for both my domain names. Is it possible to tell dovecot to use both , depending on client access; clients using the mail1.domain.tld be served by the mail1.domain.tld .key and .cert and those using mail2.domain.tld be served by the mail2.domain.tld .key and .cert

Thanks in advance Dimitrios
