I managed to get multiple SSL certs working on multiple virtual
IPs on the same server so vhost domains appeared to be completely
independent from the base server. I'd like an opinion as to whether
this is the right or best way to do this... domain1.com = 12.34.56.78

This change all SMTP server responses that depend on the
myhostname settings.
Any thoughts or suggestions on how to improve this strategy?
Use separate MTA instances.

The Postfix smtpd(8) service does not support SNI-based certificate

Your approach seems applicable to me. I have set up postscreen from

your setup?
