exchange-2013

I have an Exchange 2013 server accepting two domains: domain1.com and domain2.com.

All of the exchange services (OWA, ECP, POP3, SMTP, etc.) can be found via the address mail.domain1.com.

So, in the DNS records for domain1, I have the following entries:

MX Record mail.domain1.com

A Record mail.domain1.com -> (IP Address of Server)

CNAME Record autodiscover.domain1.com -> mail.domain1.com

Now, for domain2.com, how would I set up the DNS records? Would I have the autodiscover just be a cname for autodiscover.domain1.com? Would this allow me to leverage the certificates that I have installed for domain1?
