Port 25 Blocking FAQ
  • Article ID: 4015

Port 25 blocking prevents EarthLink email from being sent out through non-EarthLink mail servers. This stops spammers from sending out large amounts of unauthorized junk email.

Question

WHAT IS PORT 25 BLOCKING?

Answer

Port 25 blocking will stop spammers from sending out huge waves of unauthorized junk email by preventing EarthLink email from being sent out through any non- EarthLink mail servers. With Port 25 blocking, anyone logged in to an EarthLink access number will only be able to send mail through the EarthLink mail servers, thereby allowing us to block spam sent out through our network.

SECONDARY EMAIL ACCOUNTS

Any EarthLink member who has a secondary email account that is not an EarthLink account or a Web Mail account, will no longer be able to send email using that secondary account's outgoing (SMTP) mail servers. You will still be able to receive email normally through these accounts, but in order to send email, we need you to make a change for us. (You will still be able to send and receive email from any Web-based mail system, such as HotMail, without making any changes to your Web settings.)

EMAIL SOFTWARE SETTINGS

In your email software, please change your outgoing (SMTP) mail server to:

    smtpauth.earthlink.net

Note: This server requires authentication using your EarthLink email address.

This server requires username and password authentication. For Username or Account ID, enter your full EarthLink email address (example: johndoe@earthlink.net) and your EarthLink password.

This will have no impact on how your sent mail appears or on the ability of people to reply to you at your secondary email account. It simply allows EarthLink to ensure that spam is not being sent out through our network of access numbers.
