Question Certificate for email (Domain)

Server operating system version

Plesk version and microupdate number

Hello,

I actually have two identical servers. On one I can specify an ssl certificate for a specific customer domain, on the other this entry is completely missing. What could be the reason for this, or how can I specify an SSL certificate for the customer's mail server?

Thank you, Klaus

Hello @KlausZ

I would assume the servers are not identical and the issue is caused by the fact the server has Qmail as its mail server. SNI is supported for Postfix only.

Some details can be found here:

Hi, no on both servers are postfix the mailserver. But i see the difference: on that server its works the imap-server is dovecot and there it doesnt work the imap-server is courier-imap. I think thats the problem, that SNI needs dovecot, right?

Bye, Klaus

Oh, yes. With Courier, SNI will not work as well. It is only Postfix+Dovecot on Linux servers.
