The exchange 2010 install documentation says I need a SAN certificate in order to receive email at mail.domainname. If I purchase a "standard SSL", will that get me what I need? GoDaddy is offering a standard SSL, 1 year, for $12.99. When I called, the sales person did not know what a SAN was in regard to Exchange server. http://www.godaddy.com/Compare/gdcompare_ssl.aspx?isc=sslqgo001a Does an SSL apply to a domain name or the fully qualified name? The documentation says I need to include "mail.domainname", "autodiscover.domainname" and domainName in the certificate. Whould that mean I need to purchase 3 SSL certificates ? thanks,
