The most common reasons for not being able to send emails through Eudora are wrong Eudora settings or blocked port 25 by the Internet Service provider.

Here are a few checks you can make to ensure the problem is not on your end:

Use the correct Mail Client settings:

     Incoming mail server (POP3/IMAP server): mail.yourdomain.com
     Outgoing mail server (SMTP server): mail.yourdomain.com
     Username: the full e-mail address like email@yourdomain.com
     SMTP authentication must be enabled for the login to be successful.
     IMPORTANT: Please do not use secure authentication to your mail server.

The most common mistake is to leave My SMTP server requires authentication check-box unchecked. This option should always be enabled since most mail servers require such authentication.

In our Email tutorials you can find detailed instructions on how to configure your Eudora to work with your web hosting account.

Check connection to port 25

The standard port used for SMTP connection is port 25. Most often the reason for failed email sending is that your Internet service provider blocks this port. If this is the case we recommend that you use the alternative port 26 for your email SMTP connection.
