It is called subjectAltName extension.

http://www.openssl.org/docs/apps/x509v3_config.html#Subject_Alternative_Name_ --- What Goetz was getting at.

 subjectAltName=DNS: mydomain.tld
 subjectAltName=DNS: mail.mydomain.tld
 subjectAltName=DNS: owa.mydomain.tld
...
So and so forth. (via OpenSSL)

I do believe that Exchange 2007 you're able to use the New-ExchangeCertificate cmdlet to create a SAN self-signed certificate, if you want to go that route. Unless you're looking to be your own CA.

Exchange 2007 will accept either a PKCS7(CER, usually) file -or- a PEM encoded CRT file.
