Question Force same domain emails to use MX records

[jenjohn]

Server operating system version

Ubuntu 22.04..4

Plesk version and microupdate number

18.0.63 Update #4

I have setup MX records to use both Google SMTP server [1st priority] and Plesk Mail Server. I have a few email accounts that use Google Workspace and a quite a few other email accounts that use Plesk Mail server. The setup works perfectly - email sent to the user at Google SMTP server is received. Other email accounts are able to use Plesk email server to receive and send emails.

However, biggest caveat is when a Plesk email server user sends to a Google SMTP server user, it does NOT go to Google SMTP server. It is received locally i.e. Plesk does not lookup MX records to recognize that this should be sent to Google SMTP server.

Is there a setting where you can force Plesk to lookup MX records everytime irrespective of sender/receiver being in the same domain?

I tried that but it disabled ALL emails to Plesk email accounts. Please note that I have email accounts in Plesk AND in Google Workspace/Gmail. I cannot disable Plesk email completely, they are live accounts. I will need Plesk to check MX records even if I am sending to the same domain.

This would be per domain, or do you have some domain with mailboxes on both sides?

 

[jenjohn]

Yes, I have a domain that has some mailboxes in Plesk and some in Google. So, cannot really disable emails in Plesk.

This use case is currently not supported by Plesk. When the email service is enabled for a domain in Plesk, email is always delivered locally rather than routed externally via MX records.

Ok. Thx. will submit as a feedback.

Unbelievable i cant believe there is no solution for this

Unfortunately, this is how the mail service works.

The email addresses should be created on only one system. Each system considers all the email addresses to be hosted on that system.

You could use a subdomain with Google mail and configure the Golgle hosted addresses to check/use the corresponding Plesk hosted email addresses.
