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:
client+client1name@domain.com
client+client2name@domain.com
client+client3name@domain.com
client+younameit@domain.com
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 client@domain.com and client+anything@domain.com only.
