Configure server so domains are using their own domains for mail over SSL?

I thought that the most recent cPanel/WHM update would allow me to use a sub-cPanel account to send/receive mail over SSL instead of using the server's primary domain name. For example, my primary server domain is mybigcorp.com and when I send/receive mail it uses server.mybigcorp.com as the mail server address. Next I create a sub-cPanel account called mylittleshop.com and it's telling me to use server.mybigcorp.com to send/receive over SSL. How do I configure our server so all domains are using their own domains for sending and receiving mail over SSL?

  Hello, To send email over SSL, SSL must be installed on domain you will be configuring as mail server. There is no such trick which will allow you to use mail server over SSL without having SSL. Regards, Sagar - Removed -

  Thanks for your reply Sagar. So if I install an SSL certificate for each domain I can send mail using each sub-cPanel's domain instead of the primary server's domain? If so, what setting do I need to change in WHM to make it use the domain's SSL (example: mail.mysmallshop.com)?

  Yes this was released not too long ago: SSL certificate per domain on cpanel, webmail, dav, caldav, and whm services (SNI). Once you install the SSL certificate on the cPanel account, you will notice the server changes from your servers hostname to the cPanel accounts domain name to use over SSL. You may not be aware but SSL's are now free as long as your web host enables AutoSSL for you, so there is no reason really why anyone cannot use their own domain as the mail server assuming AutoSSL is enabled for your accounts.

  Hello, You will able to use only those domain on which you have installed SSL. You will not able to use it's sub domain as mail server (with SSL option enabled.) If you install ssl for domain.com then while configuring mail client with SSL you must use domain.com as mail server instead of mail.domain.com because you installed SSL for domain.com. Using mail.domain.com or www.example.com will result in error. Regards, Sagar

  Okay, it appears that I have one of our sub-cPanel accounts successfully working with it's own domain name over SSL. However, when I view the headers of the email I notice that it shows the primary server account as... X-Antiabuse: Primary Hostname - server.mybigcorp.com I am just curious if this will cause any issues with some servers rejecting the message because of a domain name mismatch?

  Hello, No, you will not face any issue because it's just provide information about mail server sender used to send out email. It help receiver to track abuse sender's server details in case of abuse/spam. Regards, Sagar
