How To: Enable SMTP Authentication For Email Clients

1. Open Eudora
2. From the Tools menu, select Options
3. Select Category then check "Allow authentication"
4. Scroll down and select Ports (*see note below)
5. Change the "SMTP Port" to 587
6. Click OK

That's it!

* 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". Follow these instructions below to install the plug-in:

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". 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.

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.
