Catchall for a domain captures every mail even for an existing mailbox

[daks]

Hello, I use two domains A and B.

A is my main one, and in B I want:

• a dedicated mailbox with is used with IMAP
• a catchall which redirects to user@A

I had this setup in my previous mail setup but I just discovered that in DMS every mail to B is redirected to user@A

What is the solution to this problem, do I need to add a 'fake' alias otheruser@B to itself (seems weird)?

Note: my catchall is implemented by an alias in postfix-virtual.cf @B user@A

OK after a better search I found some issues and conversations here, one pointed me to https://serverfault.com/questions/560906/postfix-virtual-aliases-and-catchall-for-undefined-addresses

So I added otheruser@B otheruser@B to postfix-virtual.cf
I added it manually because the setup tool does not allow to do it.

I am not sure if I found the main issue tracking this problem but I would like to eventually help with ideas

I am pretty sure you found the right tracking issue, you'll find DMS v15 docs for account management has documented this caveat for catchall/wildcard aliases and the limitation we impose.

So you are correct to use the manual config adjustment in the meantime. It will be some time before I can likely revisit the issue myself as it's low priority over many other items on my backlog.

maybe #3022?
