- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL

Hi,
we have two mail servers and one domain. For example, there are s2 and the domain test.com.
s21 is a production server, but on s2 we want to place a user who will send a message from the test.com domain to s1 users in the test.com domain.
At the moment it is impossible, because from s2 it gets the information that user xxx@test.com does not exist on this server, which is logical because there is no such server. How to make iredmail and postfix not check for local user presence, but just send email to user@test.com, then mail will go to s1 because that's what MX records indicate

Re: smtp priority

That's not how MX records and priority work. They are "service" based in that if s1 doesn't respond, try s2.

But if it hits "no such user" that's fatal and the sending server should stop there with no further attempts.

If you only have one domain, can you assign an FQDN like "mydev.test.com" then users on that will be address/account xxx@mydev.test.com?
