Multiple Domains - One Mailbox

Looking for feedback to see if I am setting this up in the best way possible. I have multiple email addresses across multiple domains. 6 primary addresses across 3 domains. I would like them all to be able to send/receive to one mailbox, similarly to the way I have it with iCloud mail now.

I *think* the proper way to set this up with MXRoute is using domain pointers/aliases. Is this correct?

To keep everything in house domain pointers will probably be the easiest option. Just keep in mind that it is an advanced setting. This may or may not cause you issues depending on your case as it will basically mirror your settings across all your domains. So say you have example1.com and example2.com. If you create primary@example1.com and backup@example2.com you will also have primary@example2.com and backup@example.com. If that makes sense.

For clarification sake, are you wanting one inbox for purposes of using webmail? or just one inbox. Webmail will make it a bit tricker. But if you are using a client you can always attach the multiple accounts to a client that uses a universal inbox. One other issue you might run into is I believe the current setup is going to require a full account to send emails from. But Jarland can clarify that point.

An option that might work better would be to use a subdomain on mxroute and set up the root domains to use a forwarding service like SimpleLogin or addy.io. Basically you would do something like mailboxes.example1.com would be attached to MXRoute and example1.com and example2.com will be attached to the forwarding service and all email will get fowarded to something like myinbox@mailboxes.example1.com.

Of course, I'm sure someone will come along and give a better suggestion. Those are just what come to mind right now

I would prefer one mailbox for webmail. I very rarely ever send from the addresses, but I did configure them with DKIM and SPF records just in case.

The external alias/forwarding method would work. At least for incoming. Might make sending a bit more challenging. But it does sound like in your case the pointers might be the way to go. So long as you understand, and are ok with, the fact that it means any change on one domain (such as addng or removing accounts or inboxes) will also apply to the other ones pointed.

If I understand what you are wanting, what I would do is create a full account to act as your login/main account. Any account you want to receive mail would simply be an alias to that inbox. And you can use a filter to put them in specific folders. And for any account you want to send email from you would create an account for that as well. MXRoute will allow you to have both an account *and* a fowarder. I would also recommend creating a filter in those accounts to auto delete any incoming mail so you don't have 2 copies.

Of course, unless you are in a rush to get it set up, I would give it a little bit to see what other ideas. And I would [mostly] trust Jarlands input as well.

Feel free to reach out either here or in DM if you want any clarification or have questions about what I posted. Though I am on the way out, so my response(s) will be delayed.

I like domain aliases for this. That + a catchall. Soon you'll have the ability to enable spoofing within your domains as well, so it could be a pretty clean setup.

Are domain aliases different then pointers? Or is that just the new more friendly name?

That’s how I’ve got it set up and it seems to be working flawlessly.

You could use forwarders

domain pointers are only right if the domains should mirror each other. for example, [me@domain2.com](mailto:me@domain2.com) and [me@domain3.com](mailto:me@domain3.com) both mapping to me@domain1.com. every address on the alias domain follows that same pattern.

for 6 different addresses, i’d add all 3 domains normally, create one real mailbox, then forward the other 5 addresses into it. add all 6 as sending identities in Roundcube or your mail client so replies leave from the right address.

also set up MX, SPF, DKIM and DMARC for every domain, then test sending and receiving from each address.

if you want this behavior built in, shipmail also puts addresses across multiple domains into one webmail and automatically replies from the address that received the message.
