multiple ssl certificates per mta

[simred]

Hi,
we have ZCS serving multiple domains. We have 1 dedicated smtp server running Zimbra MTA (mta only).
We would like each domain user can send emails using smtps protocol. The public smtps hostname should be specific to a domain. Those smtps hostnames should be mapped to the same MTA ip (by DNS).
The question is: does Zimbra MTA supports multiple ssl certificates (a specific ssl certificate per domain)? (...like Zimbra Proxy successfully implements for imaps)

P.S. we need this because we would like to do rolling domains import from an exiting zcs installation.

Tnx & br,
Simone.
