How can I block email addresses in catch all?
-
Hi.
I've got a question.
I can activate the "catch-all" in the mail settings, so that all emails are forwarded to a mailbox.
Then I can enter a random address on any page, because everything is forwarded (e.g. cloudronforum@cloudron.com).
If an address is now leaked (cloudronforum@cloudron.com), can I prevent all emails sent to this address from being forwarded? The other mails should of course still be forwarded...
Is there such a black list? -

Collecting mail via catchall is not common but I have a pretty messed up solution to you problem ^^ You could create an actual inbox for the address you want to block and delete or reject all incoming mails via a mail sieve filter. To make it easier, every time you want to "block" another incoming address, you could make it an alias of said "special" mailbox.

No, to the best of my knowledge it applies to any addresses in the mail. In any case this is how I prevent these kind mails from popping up in my mailbox.

That could work as well, but another mailbox is not necessary. You can just filter on the recipient address.
