Hello,
I have one VPS with multiple domain and SSL.

I would like that, when a user logs  to a domain  the certificate associated with that domain will be returned to him.

How can i make it ?
My VPS has actually 2 VPSs.

Thanks in advance

What do you mean "returned"?

By that, I mean the certificate that is sent to the MUA.

I might be wrong, but i don't think Dovecot/Postfix supports reading SSL certs per-virtual domain. It uses the cert that is bound to the $hostname of your box.

One way to overcome this is to have the MUA use $hostname as the hostname for POP/IMAP/SMTP. It will accept the cert(assuming it is a Let's Encrypt cert).

Dovecot and Nginx support this, but not Postfix - it loads only one ssl cert/key. Or, run  multiple postfix instances to load different certs/keys.

I suggest requesting a letsencrypt cert to include all domains you need to serve the ssl services.
