Depends on exactly how you want it changed. If you want it to be
underlined if the mailbox has unread messages, period, than that's not
possible. This is a long-standing bug IMO.
What is possible is to set after how many days unread messages should
still trigger the underlining. There's an x-eudora-setting for that:
<x-eudora-setting:9603>.
But it has some way too low maximum to be practical. Messages that are
sent with a wrong date, set back some years, will still slip into the
mailbox silently. If you have a mailbox sorted by Date this really
sucks. I wish this would get fixed.

It's called the "Out" box.

Not that I know of. But you can always submit a feature request.
