My Ubuntu server is using Exim4/Courier for emails and I'd like to know if it's possible to create dynamic email aliases for receiving emails like this:
[email protected]
[email protected]
[email protected]
[email protected]
One single account, infinite aliases that you don't need to create explicitly.
That's different from a catch-all address because, well, it caches everything (including spam). With such aliases, you receive emails sent to [email protected] and [email protected] only.
