SMTP Auth Setup for Eudora 5.0 and 5.1

  1. Open Eudora. Select the Tools menu item and choose Options. If you are on a Macintosh, select Special menu and choose Settings.

    Under Category, select Getting Started.
    Put a check in Allow Authentication.

  2. Press OK.
  3. If you are on Windows and using Eudora 5.1: Click on the Checking Mail icon, and under "Secure Sockets when Receiving", make sure "If available, STARTTLS" is selected.
  4. Now scroll down to Sending Mail, and make sure there is a check beside Allow Authentication.

  5. Last, scroll down to Ports (if you are on a Macintosh, it is called Ports and Protocols) in the Options window.

  6. Enter 587 in the box labelled SMTP Port (25)*
  7. Press OK and you are done.
* If you do not find an Icon called Ports (or Ports and Protocols), your Eudora installation is missing a required plug-in, called "Esoteric Settings". Just follow these instructions below to install the plug-in:

  1. Windows Make sure the Eudora application is not open. Look in your Eudora directory for a directory called "extrastuff". In this directory, there is a file called "esoteric.epi". Just drag and drop this file into the top level of your main Eudora directory. Restart Eudora, and when you go to Tools Menu - Options, you'll see the Ports icon appear in the list.

  2. Macintosh Quit Eudora and look in the Eudora Application folder for a folder called "Extras". In this folder is a file called "Esoteric Settings". Drag this file into the "Eudora Stuff" folder, and restart Eudora. Now when you go to Special Menu - Settings, you'll see the Ports and Protocols icon in the list.
