Different SSL certificate per virtual domain

[Durga Prasad Malyala]

Hello All,
I've googled but a bit confused.
I have a server with an IP hosting two different virtual domains.
Both domains need to have their individual SSL certificate like
mail.domain1.com and mail.domain2.com to download and send the same.
Is it possible in Postfix if I have only one public IP and achieve same?
Can you guide me to some links if possible.
Thanks/DP
