Domain aliases for email

[guyds]

When you want to have the same email addresses / aliases on multiple domains, e.g. the same domain with different extensions, you currently have to set up all email addresses and aliases for each domain separately.

For example:

• address1@mydomain.com
• address2@mydomain.com
• alias1@mydomain.com
• alias2@mydomain.com
• address1@mydomain.net
• address2@mydomain.net
• alias1@mydomain.net
• alias2@mydomain.net

For this you currently need to define 8 addresses / aliases.

With domain aliases however it would be possible to set up everything for mydomain.com (the first 4 in this example) and then point mydomain.net as an alias domain to mydomain.com and automagically those addresses / aliases are also available under the .net domain.
This makes it much easier to maintain in case you have many addresses / aliases.

This can be done already in other mail solutions such as Google Workspace, Zoho mail, Mailcow, etc.

Note:
I'm aware of this other topic, but the op didn't express an explicit desire to have this happen automagically and as a result that topic was marked as implemented in 5.2 with the current, manual implementation which is not what is proposed in my request.

Just a slight correction that in your example you would only need to define 4 aliases, as you can use wildcards, see https://docs.cloudron.io/email/#mail-aliases:
address*@mydomain.com is sufficient to cover both address1@mydomain.com and address2@mydomain.com

@necrevistonnezr that's correct, but as you might understand this was just an example.
In reality it will be something like this@mydoman.com, that@mydomain.com and whatever@mydomain.com where wildcards are not a solution.
