I have set up in BIND DNS mx record but they dont work.
We can help, though we’d need a few more details about the issue you’re seeing. What symptoms are you seeing exactly?
Is this a problem for just this one domain, or for all domains on your server?
Can you post a screenshot, or a link to a screenshot, of your Server Configuration -> DNS Records screen for this domain?
And is your Virtualmin server configured to be the nameserver of your domain?
