Not unless the IP address is the "name" you use as the server address. 
By this I mean, if you have mail.example1.com and mail.example2.com both 
bound to the same IP address 1.2.3.4, then you can only have an SSL 
certificate for one of those two names or all users must refer to the 
server by its IP address exclusively (and the IP address will have to be 
the Common Name in the cert).

If you have more than one domain, and they are not related (in the sense 
that they are all known to users of each other), *and* hence you must 
use multiple SSL certificates, you must have multiple IP addresses bound 
to the server.  This has nothing to do with what CA is used to sign the 
certs.
