Somewhere along the line, a long time ago, the "name" of my mailbox was changed to "arrow". I did not initiate this change, but was led to believe that it was necessary.
When I log in to get my POP mail, I must use the "email@example.com" address. The problem is that when I send email to others when using the web interface, I (the sender) is identified as "firstname.lastname@example.org" rather than the usual "From" address that I use with Thunderbird. No one knows who I am when I send mail from the web client, and it causes me untold grief.
I need to be able to fix this problem so that my web-based email listed my preferred email address rather than the "arrow" one. When I log into Mailbox Manager, I see no place or way to change the name of my mailbox. In fact, I cannot find any location that allows me to manage the name of that mailbox. How do I fix this problem so that sent mail doesn't come from "arrow"???
