Managing Eudora Mailboxes with IMAP - The Basics

Published on WWW byDavid Nye

When you open the PC version of Eudora 5.0, the screen will be displayed like this:

Your new IMAP profile will probably be labeled <Dominant>, meaning that it is the main e-mail account you will be using. You can create new folders by right-clicking on <Dominant> and selecting New...You should actually create a new folder as a "mailbox", not as a "folder" as, in Eudora, mailboxes are the only things that can hold messages, while folders can only contain mailboxes. Any folders that you create will appear under the Inbox entry. You cannot change the name of the <Dominant> account but you can create additional local or IMAP-server based folders/mailboxes beneath the Inbox (right-click on the Inbox and select New...).

The Eudora In mailbox is for incoming POP messages (if any) with the mailboxes/folders beneath it. No matter how many POP accounts/servers you use, all POP mail is funneled into this single In mailbox.  Additionally, all your outgoing mail (even mail you send from your IMAP account) will be stored in the Out mailbox under the main Eudora account. The In, Out and Trash folders are located on the local computer. Mail in the IMAP account is stored in folders that reside on the server, not locally on your computer. This has consequences that affect disk space usage on the server (see the section on IMAP Mail Storage and Quotas below).

If you used Eudora for your old POP mail account and have any saved messages, you will need to upload them to the server if you want to make them available for an off-campus connection. To do that, you can open the local Eudora folders and drag the messages from the list in the top-right window to the Inbox folder under Dominant. Once this has been done you will be able to work with all of your mail files from any Internet-connected computer, at home or at college. Adding that functionality is the reason for the change to an IMAP based mail system.

Using the program tabs at the bottom of the folder listing, you can switch between the Mailbox view, the Personality view, the Signature view, the File Browser view and the Stationery view.

IMAP Mail Storage and Quotas

The IMAP service stores electronic mail on the server.  This obviously has implications about disk usage and the service uses a quota system that gives each IMAP user a limited amount of disk space. The quota should be more that adequate for most users, but warnings will be sent via email when the amount of mail stored exceeds a percentage of the quota. 

It is important to clean up mail that you have read and/or responded to, otherwise you may exceed your storage quota and no mail will be delivered to your account and your mail will "bounce" back to the sender. Once you have read, responded to (or forwarded, etc.) mail, you can delete it (see below) or save it to a different folder either locally or on the server

With Eudora, messages remain on the server until you actually "purge" them from your mailboxes.  This is a separate action from the Delete command.

To delete a message, you need to take two steps:

  1. Mark the message for deletion by highlighing the message then either pressing delete, or selecting Delete from the Message menu
  2. Remove ("purge") all messages marked for deletion by selecting Remove Deleted Messages from the Message menu (after you execute this command the messages cannot be restored).

To save a message to another folder either on the server on the local computer, just 'drag and drop' to the new location.

Resynchronizing an IMAP Mailbox or Folder

Keeping your mailboxes and folders remotely on the IMAP server lets you perform operations on them from different computers. For a particular IMAP mailbox, you may delete some messages from the mailbox from one location, check mail from another location (resulting in new messages being transferred to the mailbox), and change the status of some of the messages from a third location.  Each computer has no idea what has been done to the mailbox from the other computer until you resynchronize the mailbox, which updates all operations performed on the mailbox from all computers that have access to the mailbox.

To resynchronize an IMAP mailbox or folder, do the following:

Resynchronisation will also take place automatically each time you start up Eudora and log-in to the IMAP server

Online/Offline viewing

When using IMAP, your mail is stored on the server and you will most likely remain connected to that server while you are reading/composing e-mail. However, it is possible to work in offline mode, in which case you will work on a local copy of selected folders. When you reconnect to the network, Eudora automatically synchronizes any changes you made when offline. You can also synchronize your mailbox manually at any time.

Configuring for Offline Reading

The default setting in Eudora is to download "Minimal headings only ".  This would only actually download message headers to your PC with the actual body of a message being downloaded on an individual basis when the message is selected for reading.This option would leave you without message texts if you disconnect.  To change this option:

Viewing/Reading Mail from Different Locations (Roaming Configurations)

Users may want to duplicate their configurations for the different locations from which they may access the IMAP service.  You will probably want to duplicate your Address Book at each location (the NNDBASE.TXT file).  Other configuration files include EUDORA.INI, signature file(s) (STANDARD.TXT e.g.), and any filters files (filters.pce).
