Question Email Relay for specific Domain

[daanse]

Hi,

i have a Customer with a Domain at Plesk.
Domains DNS is managed over external DNS Server.

The Customer Uses an Exchange Server with that Domain.
Only one Email he has setup in Plesk and he receives Emails.
But if he wants to send Emails (i.e. to some Colleagues with same Domain i think) it wont work. Plesk/ The Email Service for that Domain looks only on Internal and fails if it finds nothing.
Can't we set something to say to Email / Postfix should also respect external MX of Domain?

Hope you understand, can't explain that good.

We should say "Plesk, if you don't find a internal Account, please look in the World Wide Web for that too, not just cancel"

Would this be possible but leaving the Email Functionally for this one Mailbox still working?

System:

Plesk 17.5
Debian 8.x
Postfix
Dovecot

If I correctly understand the question, you can't configure work properly all emails accounts on Exchange and one additional email on Debian/Plesk/Postfix/Dovecot for the one domain at the same time. You should use a different domain for Plesk or you can create a subdomain.

As an example with subdomain:
- Exchange: [email protected], ..., [email protected]
- Plesk: [email protected]

Hi, yes.
I found an Article yesterday and wrote there: Resolved - Relay mail for specific domain
Still not Found a working Solution yet but hey...

We would really need a Domain Based Mail Relay Option as requested several Times in Plesk Uservoice
