Common outgoing mail servers to cure relaying error
Visited: 4008 Did this article help? yes | no
You may be using an outgoing mail server that is different than your ISP's and your ISP may be blocking port 25 (smtp mail) to prevent spamming. In these cases, you should configure your email client to utilize your ISP's provided email server. Note you are typically assigned a username/password and will often need this to send mail through your ISP's mail server (different from your incoming mail username/password).

In Outlook Express or Outlook these settings are under Tools, Accounts, Mail. Look for Outgoing Mail Server (SMTP) settings.


Incoming/Outgoing Information for Major ISPs
You may recieve a message that includes the words "We do not relay" followed by your email address, or a message containing "Relaying prohibited" when you try to send an email.

On some occasions an ISP (Internet Service Provider) will block port 25 traffic. You will need to use your outgoing mail server information for sending mail. Below are some of the major providers and their server information. You'll only need the outgoing server information.
