Using "Add alias" to create a blind mailbox for relaying domains #2905

Open marrco opened 5 years ago

On a secondary mx (or a backup server, or just a relay gateway) when creating a Relay domain it's good practice to have a list of all mailbox. And the suggestion is to create a "blind mailbox" for every single recipient.

I see that the actual "Add alias" form already has a few checkboxes on the bottom (silently discard mail, learn as spam/ham). I don't know where all those options hook into the mail flow, so I'm wondering if it's an easy feature to add a checkbox there to [ ] Create blind mailboxes

I see MC working well as an antispam proxy in front of exchange and many other servers, that would speed deployment time a little.

We could add an option to sync settings of two mailcows via API. Needs more API endpoints, but could work.
