We currently have a qmail set up as an email gateway for incoming mail, and from there it is routed to a different internal mail server based on smtproutes.
Is there a way that we can have one domain forwarded from the qmail 'gateway' to multiple internal servers? For example, when someone will send an email to [email protected], it gets routed to our qmail server, and from there a copy is sent to both mailserver1.example.com and mailserver2.example.com - both of which have the same list of users and both of which think that they are the mailserver for example.com
Thank you.
