I thought I understood "Alias domains" as that it's simply an alias for another domain! So when I set up a mailbox like "email@example.com", and add "alias.com" as a domain alias for "main.com" the address "firstname.lastname@example.org" would also work... But no!
So, I've added these domains:
I've created this mailbox:
Then I mapped these alias domains:
- alias.com => main.com
And then when I send a mail to email@example.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
So... what are these exactly?
