[Dovecot] Two server certificates for two common names

[Δημήτριος Καραπιπέ ρης]

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
