    I will explain what i want:
    I have the "main" domain on my server,, and everything is working flawlessly. I also have few others domains,,,, installed on this sever. To access emails for the second domains over SSL I use (main domain) as mail server and all works fine.

    A client of mine wants to host his web host with us and he wants to provide his clients the ability to access their emails at over SSL. I know i can add a domain and setup a SSL for it under website but my question is: won't my server read the root SSL? The main domain SSL? Also, for theis new "main" domain, can I setup and so my customer can give that to their clients istead of If yes to all of these questions, how do I do that? How do i need to setup the dns zone for the

    Sorry about the noob questions.

    Thank you,

    Your client needs a own IP. POstfix does not support SNI.

    You need an additional server for smtp/submission/smtps for postfix (look at the and read and override the relevant settings with " -o <value>"
    You may have to adjust dovecot, too.

    OK. So it probably would be safer to just put the new guy into a new guest and move on, eh?
    Thank you.

    A VM is always safer as you get a completely separated OS enviroment. So if you have the capability to run an additional VM then I would do that.
