I thought I understood "Alias domains" as that it's simply an alias for another domain! So when I set up a mailbox like "info@main.com", and add "alias.com" as a domain alias for "main.com" the address "info@alias.com" would also work... But no!

So, I've added these domains:

  • main.com
  • alias.com

I've created this mailbox:

  • info@main.com

Then I mapped these alias domains:

  • alias.com => main.com

And then when I send a mail to info@alias.com I receive this error:

Recipient address rejected: User unknown in virtual mailbox table (state 13).

I don't want to create an alias for every domain, as I have a few. I also don't want to use a wildcard (like info@*) because there are also other domains that aren't aliases of main.com

So... what are these exactly?

The explanation is in the documentation: http://www.postfix.org/VIRTUAL_README.html#virtual_alias

You want "alias mailboxes" aka virtual_mailbox_alias and virtual_mailbox_maps but talk about "alias domains": http://www.postfix.org/ADDRESS_CLASS_README.html#virtual_alias_class
