Issue Mail Certificates & iPhone

[bradz]

Hi
My servers are running
CentOS Linux 7.9.2009 (Core)
Plesk Obsidian Version 18.0.32

This has been an ongoing issue for me. I have spent a lot of time on the phone with Apple support trying to convince them to add button to accept cert when it happens or like the android, an accept all certs option during setup, but no luck. It happen when the cert is renewed.

Question, Is a Plesk up in the works that will allow the mail server to present the cert of the domain and not the cert of the server? This occurs when using a shared IP.
Please, this will be a huge help!!!
Sincerely,
Brad

I suppose that you have to enable SNI support for your mailserver as it is described in this KB article How to assign a SSL certificate per domain to secure the mail server in Plesk (SNI support)?

Thanks so much Igor!
Question, will this support be added to Courier mailserver?

My servers show Installed IMAP/POP3 server Courier-IMAP

Or how smooth is it to switch to Postfix + Dovecot
thanks,
Brad

AFAIK, Courier is not supported by SNI.
IMAP/POP3 server you can change here:

Your the best Igor!
Any down side or risk I should consider before switching a server with many domains and emails?
Again thanks, this will be a big help!!!
Sincerely,
Brad

Thanks Peter! Very helpful!
This brings me to something I have wanted to do but had not figured out, however it was low priority.
To send a notice to all emails asking them to make sure folder names are fine,
Plesk has the

Send Mass Email Message​

I made the message and selected All Emails but I get
Error: Unable to send mass mail, no email addresses selected.

Looks like it is time to use this feature
I will next look for docs on this.
Thanks,
Brad
