catchall -> mailing list?

[drew]

I've got some rando extra domains that I use for various projects or low-volume contracting in different fields. I have no interest in connecting mail clients to them individually but sure would like to be able to use them in contact forms, hand them out to freelance clients, or whatever if I wanted to. I get that you might need to rework some plumbing to have a catchall on a different domain and this probably isn't a common enough use case to justify it, but why can't I just point the catchall at a mailing list?

Sounds like a edge case. You could catchall with an normal account and automatically forward to a mailing list.

[drew]

@subven Could I do that without connecting a client to like 10 different domains I want to forward but don't need to get mail on?

For sure an edge case, but probably an easy one to satisfy that wouldn't challenge any user-facing functionality.

@drew yes you can. Forwarding will be possible without a client connectet. You have to create sieve filters. Take a look at the documentation.

Edit:

quick tutorial how to catchall and forward to another address

1. create user for catchall
2. create mail address for every domain you want to collect and assign it to the user
3. go to Email --> domain and select the the inbox you created as catchall
4. Install Roundcube
5. log into one of your catchall inboxes using the (full) email address and users password
6. create managed sieve at settings --> filters

7. repeat for every domain you want to collect

One issue I ran into while trying to forward mail is that the provider you're forwarding to needs to support SRS. I wanted to use Proton Mail but their support told me they don't support SRS so I often have mail bounce back.

The one question I get when reading this is: why a mailing list?

A mailing list is there to distribute a single email to a group of recipients. Can your request maybe also be understood as "give me the ability to select a mailbox on a different cloudron hosted mailbox" or even "give me the ability to specify the recipient email of a catch all rules"?

[drew]

@fbartels Indeed, either of those possibilities would satisfy my use case. I think I invoked the mailing list feature in my post because it was at the end of my path in attempting to implement this and it seemed like a simple enough add-on— but, of course, I know nothing of your app architecture! Multiple recipients aren't a requirement.

[drew]

@subven Personally, I wouldn't even need that. Any correspondence going forward I'd probably just do from my primary address. Just a regular forward would be fine. I imagine that would be a pretty common requirement people would have in this context though.

[drew]

@subven Yes— I understand that I can do this through a mail client like round cube, but I was hoping not to have to.

Just to have it said. setting up these rules is a one time thing. You just have to create a single rule per domain, and no further connection is needed.

If you have a lot of domains and want to automate it, you could even script it through https://manpages.ubuntu.com/manpages/trusty/man1/sieve-connect.1.html.
