if you have SIP and SMTP (primary) different, then you need to make sure that autodiscover works ok.  You can redirect _autodiscover._tcp_smtp.domain to autodiscover.another.smpt.domain 443 if the later is defined and works ok.  Then you do not need to worry about UC SAN SSL.

With autodiscover.smpt.domain SFB client will try to connect directly, with SRV you can redirect to another domain.
