Not quite it
What I'm looking for is to know that when you're in a certain folder, your mail will go out as user "foo@example.com", but in all other folders, it will go out as "bar@example.com". This is configurable under, eg: mutt, as a folder-hook. Does Eudora have a similar option?
Seems that there is the ability to select who you want to send mail as from the "From" dialog. This would appear to address most of the concerns we've got.
