Question How to host mail server in Plesk but domain with Squarespace, but SSL secure IMAP and webmail?

[harry_pipeline]

Server operating system version

Ubuntu 22.04.1 LTS

Plesk version and microupdate number

Plesk Obsidian v18.0.48_build1800221104.03 os_Ubuntu 22.04

As described in the title..

I have mydomain.com.

The DNS server for mydomain.com is Cloudflare.

The A record for mydomain.com points to my Squarespace website.

I want to use Plesk for mail, but I cannot add a wildcard/mail domain SSL to secure webmail.mydomain.com and Mail access (IMAP, POP, SMTP) without it requiring the A record point to Plesk server as well. See this screenshot where the "secure domain" is undetectable: https://cdn.zappy.app/6e0d824692ac540f4c74c2c7c577c8e5.png.

Can someone help me configure this?
Thank you!

Issue a certificate just for webmail.mydomain.com so you can access webmail via your domain. For mail access over IMAP, POP and SMTP you can use your servers host name instead when making connections. Which should work just as well.

Thanks Kaspar, but I still don't understand.

My hostname is something like this: epic-test.123-123-123.plesk.page, and mydomain.com is just one of many domains I have listed.

The email account is [email protected], and when using an iPhone for Mail, I need to enter the Incoming Mail Server and Outgoing Mail Server, which I'm not sure what that is.

Set your hostname to something like server1.domain.com and use that for the IMAP/POP/SMTP connection.

As @maartenv suggested change your servers host name. How you do this is explained in this article:

Awards make sure you also configure the Reverse DNS your servers IP. This is done trough your provider. Contact them for assistants.
