Using FastMail with Eudora for Windows

Note: If you already know how to set up your client, and you already understand the information below, see this help page for the server information you need to set up your e-mail client. The Troubleshooting Issues section at the bottom of this page may be helpful if you have problems.

In order to use Eudora for Windows with FastMail, you'll need to enter the following information:

  • username - When you signed up for FastMail, you chose a username which is also your e-mail address. You must use the full username, including the name and the domain part, which is the part after the '@' symbol. For example, a user named John Doe might have chosen a username of "". Make sure that you specify your username in lowercase only.
  • password - When you signed up for FastMail, you chose a password to go along with your username. You will need the password to access your account. The password also keeps others from being able to access your e-mail. Your password is case sensitive, so be sure that you type it in correctly. "PASS123" is different to  "pass123". Often, users forget about the CapsLock button and mistype their password.
  • incoming mail server (IMAP or POP) - This is the server that you get your e-mail from. Internet Message Access Protocol (IMAP) and Post Office Protocol (POP) are retrieval methods used to move e-mail messages from the server to your e-mail client so that you can read your messages. POP access is not available for all service levels, please check the pricing table for details. Secure Sockets Layer (SSL) is required for your protection as well. SSL keeps people from reading your e-mail as it is transmitted between the e-mail server and your computer.
  • outgoing mail server (SMTP) - This is the server that sends your e-mail. Simple Mail Transfer Protocol (SMTP) is the method that your client uses to move e-mail messages from your client to the server so that it can send your messages. The FastMail SMTP server is not available for all service levels, please check the pricing table for details. If your service level does not allow use of the FastMail SMTP server, you must use the SMTP server provided by your Internet Service Provider (ISP).

    The FastMail SMTP server requires SMTP Authentication. This keeps people who are not users of the FastMail service from using the SMTP server to send spam messages on the Internet. SSL is required for the FastMail SMTP server. If you don't use the FastMail SMTP server, you may have different options or requirements. You will need to get that information from your ISP.

Incoming/Outgoing Server Setup

  1. Open Eudora and select the 'Personalities' icon in the bottom left-hand corner of your mail folder list. Right click inside the 'Personalities' tab and select 'New...', the 'New Account Wizard' window should appear.

  2. Choose 'Skip directly to advanced account setup' and click 'Finish'

  3. In the 'Generic Properties' tab, set these options:
    • For 'Personality Name', enter FastMail account, or something else you can recognize easily.
    • For 'Real Name', enter the name you want people to see beside your email address when they receive email from you.
    • For 'Return Address', enter your email address.
    • For 'Login Name', enter your username/email address as described at the top of this document.
    • For 'SMTP Server', you have to enter '' in the red box.
    • Select the 'Authentication Allowed' checkbox.
    • The rest of the options should be set as in the graphic below:

    Note: Guest users do not have access to the '' SMTP server. Member, Full and Enhanced users do have access to the '' SMTP server, so the following does not apply. Guest users should instead set the 'SMTP Server:' field to your ISP's SMTP server. You should be able to find this information in your ISP's documentation; we don't have the information, so please don't email us asking what it is. Also, depending on the strictness of your ISP, you may also need to set the 'Return Address' field above to your ISP's email address. The only way to be sure of if this is required or not is to try and send an email, and if you get an error, try again after changing to your ISP's email address. Finally, you should make sure that the 'Authentication allowed' checkbox displayed above is NOT checked.

  4. In the 'Incoming Mail' tab, you probably want to have your settings exactly as shown.
    Remember a few things:
    • The 'Server' entry is now '' in the green box.
    • You probably want to use the 'Minimal Headers only' option.
    • You definitely want to set 'Required, alternate Port' for the 'Secure Sockets when Receiving' option.
      This encrypts the e-mail transmission between the e-mail server and your computer, so it's for your eyes only.

Click 'OK'.

You should now see a 'Yourdomain Account' folder in your folder list. by right clicking on this folder, you can choose 'Refresh Mailbox List', and right-clicking on any of the folders that appear allows you to Synchronize the e-mail on your computer with the e-mail on the FastMail server.

When composing a letter, you can send e-mail from your FastMail account even if it isn't your dominant account. Just select FastMail in the drop-down list that appears when you click on the 'From' icon in the composition window.

Learning more about IMAP

IMAP is a powerful protocol that allows you keep to your email synchronised, whether you're at home, at work, at a friends place or an internet cafe. You don't have to worry about what computer the email is on, because all the email is kept on the server and each client sees the same 'view' of the email. See this FAQ page to learn more about IMAP

Troubleshooting Issues

  1. You get a "Server SSL Certificate Rejected" warning when connecting via SSL
  2. Eudora 5/6/7 does not have the root certificate of our SSL provider built in. For Eudora 5/6, you can follow the directions here to add trust for our certificate. For Eudora 7, when the error window pops up, there should just be a "Yes" button at the bottom of the dialog you can click to accept trust for the certificate.
