Question New Plesk user : SSL configuration question

[Gaylord]

Hello and sorry for my bad english, I'm french

I'm new Plesk user and I like it. But I have a question.

I have a SSL Certificate (GlobalSign) for domain.com, www.domaine.com and mail.domain.com. I succeed install in my domain.com and www.domain.com.

But now, I want to install my SSL Certificate for my mail serveur. I have Postfix, Dovecot, Debian 8 and three ssl files (.crt, .key and .pfx).

Can you help me ?
I am not very strong on server but I am not afraid of the lines of commands
Thanks very much

Just go to Tools&Settings->SSL/TLS Certificates and use needed certificate for option "Certificate for securing mail".
