individual "mailing list" for each receiver

Yes, exactly.

then I think you could (ab)user the mailing list feature of Cloudron for that https://docs.cloudron.io/email/#mailing-list

That's what I was thinking.

• provide an email address name@family to people
• user that don't have a cloudron account already should get their mail delivered to an email address at an external provider
• cloudron users could have their mailbox on cloudron

As long as you don't want people to be able to send with their @family address, then I think you could (ab)use the mailing list feature of Cloudron for that https://docs.cloudron.io/email/#mailing-list. Just don't restrict sending to members only.

Regarding the previous reply:

@dsp76 said in Easy way to handle mail forwarding without setting up accounts for each?:

assign aliases to it

No, not aliases. But Cloudron treats mailboxes and Cloudron users separately. A mailbox can belong to a user or group. And each user can be the owner of multiple mailboxes. So you could have a dsp76 account on your cloudron and make the mailboxes father@family, mother@family and third-cousin@family and assign them to dsp76. Then you can use roundcube and login user father@family as the email address and the password of your dsp76 users. This way you could easily log into the individual mailboxes and setup rules for forwarding. But that is too much work and I would rather recommend the mailing list trick I already wrote about.

At my current provider I can setup a list of emails for a domain and set their forwarding addresses. There isn't even a mailbox assigned for each email address.

Is there such a simple way?

As far as I understood your suggestion, I could setup one account, assign aliases to it and set individual forwarding rules for each address?
