Is it possible to have more than one mx for your single domain? Problem is that I am going to migrate some of my staff to our web hosting company which offer mail for free so I want to test it. Route all mail to our hosting company and for addresses that are not recognized will then be forward to our local mail here. Has anyone know how to do it?

You could always make a subdomain to do the testing on, that can have a different MX.

What I've done in the past is setup..

maindomain.com

And

maindomain.net

with different MX servers.

Any mail delivered to maindomain.com I've setup as a forward to the same mailbox at maindomain.net

Maindomain.com is a unix/linux qmail server. Maindomain.net.au is an exchange server.

A single domain zone (maindomain.com) can have multiple MX servers, but these should be considered as one unified system, just acting as backups for one another.

As Andrew says, subdomain.maindomain.com can have a different mx server or multiple mx servers, so you can have username@subdomain.maindomain.commailto:username@subdomain.maindomain.com go through to its own MX server for testing, or, you could setup a redirect for username@maindomain.commailto:username@maindomain.com to redirect / copy mail to username@subdomain.maindomain.commailto:username@subdomain.maindomain.com while you test it out.

Good luck.

Hi Tarau

Yes it's possible to add more than one MX record for a domain, however purpose of doing this to add reliability in case if the primary MX is not reachable.

What you want to do , is to route mail that should go to free web hosting company from that MX record.

an explanation can be found below link with some MTA setup sample.
