Summary

This feature would allow domain owners to create email address aliases that match a wildcard pattern.
For example, if I have an email address [email protected], I should be able to create an alias ellen*@wayland-yutani.terre -> [email protected]
That way, I can give out email addresses like [email protected]

Motivation

This feature is request by Algoo for the Galae project.

Additional context

To implement this feature, we need to add two things into the UI:

• A new option into the domain configuration of the global administrator. To avoid confusion, we should call it "wildcard aliases" or something similar. The option should be a boolean, and it should be disabled by default to preserve the current behavior.
• A information point into the alias creation form, to explain the feature is available (or not) for the current domain. And a red mark when a wildcard alias is present in the alias listing.

See the mockup below for an example of the UI:
