Question Use external mailserver for single Domain

[YannikSMYLIE]

Hey everybody!
I am hosting serveral sites on my PLESK Server. Some of them do use the integrated mailserver, some don't. My configuration is some kind like this:

1. Site A with disabled mail service (the MX record directs to IONOS)
2. Site B with enabled mail service (the MX record directs to the Plesk Server)

I can send and receive mails from and to both sites, this works totally fine.
BUT: If I try so send an E-mail from bar@siteb.de to foo@sitea.de it does not work because my SMTP Server recognizes, that Site A is on the same server and tries to send the Mail to this mailbox. BUT I am not using the mailservice for Site A on the Plesk Server, so it is telling me that it did not found any inbox called foo@sitea.de and refuses to send the mail.
Also it totally ignores my MX Records...

Any idea how I can fix this problem?

Thank you very much and stay healthy!
