Virtual Email Domains using different SSL Certificates
Greetings everyone,
I operate a Mac OS X Server (10.8.2) which has four static IPs assigned.
Amongst other services, the Server hosts mail for 3 domains and each domain has been assigned a mail server address on a different IP:
173.X.X.216 -> mail.domain1.tld
173.X.X.217 -> mail.domain2.tld
173.X.X.218 -> mail.domain3.tld
Both forward and reverse DNS work fine and email sent and received is operational for all domains using virtual mailboxes authenticated via Open Directory, i.e.:
user1@domain1.tld also receives mail at user1@domain2.tld and user1@domain3.tld
So far, everything is operating as expected.
Where I have run into a roadblock is that I would like the mail server for each domain secured with it's own SSL certificate and the Server app only allows me to define a single certificate to use for all Mail services. Indeed, if in the Certificates section of Server app, if I define the SSL certificate issued for one mail server's hostname/IP, users connecting to the other two servers are warned that the certificate is not trusted because of a hostname/IP mismatch.
Is there any way to use a separate SSL certificate for each virtual email domain, or am I forced into having all users authenticate through one server if I am to avoid the untrusted certificate warning?
Thanks for any insight you can provide!
All the best,
Edward
