Plesk: Domains with own SSL certificate for IMAP/POP3/SMTP
Hey guys,
I would like to hear the opnion of you on this topic.
I'm testing Plesk and I'm trying to set up for each domain use its own SSL certificate to access IMAP / POP3 / SMTP.
client1 ---> IMAPS -> mail.domain1.com
client2 ---> IMAPS -> mail.domain2.com
client3 ---> IMAPS -> mail.domain3.com
I researched and found that the Dovecot supports SNI (Shared IP). Unfortunately Plesk only offers this feature via an extension and only allows one certificate per domain if each domain has a dedicated IP.
Here are a few considerations on the scenarios that I see:
1 - A hostname/ssl by server: srv01.mydomain.com.
All users would access the IMAP/POP3/SMTP settings with the same address. But if I need to migrate domains to other servers? Users will have to change your settings in email clients. It is not good.
2 - centralized mail server.
Users also would access a hostname with mail.mydomain.com certificate and if the domain change server, e-mail settings do not alter. The problem is that Plesk does not offer this feature.
3 - self signed certificate.
The easiest to implement but less secure.
- What do you think?
- With cPanel is easier to solve?
- How do you solve this?
