 David J Taylor <my-email>  my-email (in italics)

First post,so forgive any incorrectitudes! Imported a large collection of messages from Windows Live Mail 11 into Thunderbird, where I had already set up newsgroups. Created a new folder "D" into Local Folders and imported there, but two issues: - folder "D" shows (right-click, properties) like a newsgroup - it has General information and Retention Policy tabs. Maybe this is OK? - when replying to a message it appears to be using the wrong account. In the From line it shows: David J Taylor <my-email> forums.embarcadero.com (in italics) and a Newsgroup line (blank). whereas it I create a new e-mail using Write, the From shows: David J Taylor <my-email> my-email (in italics) and no Newsgroup line. I don't understand whether this is to do with the e-mail properties (the one I'm replying to) or whether it's a property of the folder tree I created. I have searched for a solution but not found one. Is there a way to fix this, please? Thanks, David
