As far as I know, dnsdist can't generate MX records, so you'll have to do
this in the PowerDNS Recursor. Sorry!
In the Recursor it is not very hard to do though, use postResolve to
override all MX records you see in responses.
This makes sure you don't invent MX records for domains that don't have
Also be aware that if there is no MX record for a domain, a mail server
might decide to send email directly to the A record.
