I have to admit: I’m really puzzled by how e-mail addresses work now.
Last night, I set up a new address and it automatically set up a corresponding mailbox into which (it says) it will put the mail to that address. Let’s say the username is FRED and the mailbox is m1234567.
When I then go to Squirrel Mail and log into email@example.com, I go to a mailbox full of the right messages. When I go to Squirrel Mail and log into m1234567, I wind up in a mailbox for a different address at my domain.
Shouldn’t mail sent to firstname.lastname@example.org wind up in m1234567?
Am I misunderstanding something?
