As per this older thread http://bbs.applescript.net/viewtopic.php?id=8707, I have created a script that will transfer the topmost email to an already-existing folder.
a) I need the syntax to tell Eudora to transfer all SELECTED emails to a folder; and
b) I need Eudora to create the destination folder on-the-fly within a mail folder that I will specify. I can tell Eudora what to name the new mailbox as well. It should in fact be named for the date of the email, i.e., “2007.06.03” would be today’s email. Be nice to have the argument that Eudora should create a new folder and come up with the correct name for it based on the date of the selected emails, then transfer them, instead of me doing the folder-name calc FOR Eudora and passing it to Eudora as an already-calculated string. But I can live with it either way.
