Cannot Send Emails Using Outlook Express

What to do when you cannot send emails using Outlook Express:

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

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

IMPORTANT: Please do not use secure authentication to your mail server.

Check connection to port 25
The standard port usually 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.
