So you’ve used subaddressing for a while, and now have decided to stop. Maybe you want to switch back to POP3 for some reason and want to route all mail to the Inbox rather than to folders. Lucky you, there is an alias trick to make that happen too!
firstname.lastname@example.org = email@example.com
Note that you may need to disable subaddressing for this account before this alias works.
Hopefully a few more aliasing and subaddressing tricks soon.
