Preview IMAP4 Mail
The Preview IMAP4 Mail function is activated by the toolbar button or File menu option by that name, if your General Settings notebook says that the current account is an IMAP4 one rather than a POP3 one. (Otherwise, this toolbar button and menu option will bring up the Preview Mail window instead.)
If you want to bring the contents of your IMAP4 INBOX into your J Street Mailer folders for local storage, using the Retrieve mail option is probably the easiest way. The Preview IMAP4 Mail window is mainly for interacting with the mail folders on your server, though you can also download mail from this window if you wish.
When you select IMAP4 at the top of the first page of the General Settings notebook, two extra settings appear. The top one, Mail Folder, lets you specify the server directory which is the parent of your INBOX and other mail folders. Most people will never need to type anything here, since the directory you're in when you log onto your IMAP4 account is likely to be the right one. But if you do need to specify the directory name here, be sure to include a trailing separator character. For example, if you want to say "~/Mail", say "~/Mail/" instead. This setting affects the Preview IMAP4 Mail window only. The lower setting on the other hand, Mailbox Name, has no effect on this window. It is where you specify the folder whose mail you want the Retrieve mail option to download. The default, which will work for most people, is "INBOX". If you need to change it, include the full pathname, without a trailing separator character.
When you attempt to bring up the Preview IMAP4 Mail window, one other dialog comes first: Preview IMAP4 Mail Setup. Its settings will be filled in using the information in your General Settings, but you can change the server name, userid, password, and port number as desired, if you want to work with the mail in some account other than the J Street Mailer account you have open at the moment. If you turn on the Debug Mode checkbox, the commands that the program sends to the server, and the server's responses, will be displayed in the window in which your Java virtual machine is running.
When you leave the setup dialog, then the program will proceed to the main Preview IMAP4 Mail window. This window is very much like the program's main window, with a folder tree panel, a message list panel, and a browser panel. If you select a folder, a dialog comes up to tell you how many messages are in the folder and ask you which ones you want displayed in the message list panel.
