Virtualmin server as mail only server (MX) for domain hosted somewhere else

Hi,
is it possible to setup Virtualmin server (got few other on this server) as mail only server for domain hosted on another server?
If so how to make it?

Create a virtual server that includes email and set up your DNS appropriately.

Already did this but I’m getting “521 No Redirect Entry for this address (in reply to RCPT TO command)” while sending emails to address on this virtual server/domain.

OK. Already sorted this out - the problem was misconfigured Postfix (option: What domains to receive mail for).
Now everything working like a charm.
