SMTP Authentication changes

Tech Document - T123m01101

Effective Thursday, December 20, 2001 at 12:01AM CST, 123m.com activated User Authentication on our SMTP server(s).

What this means, is that you will need to have your POP3 client software configured to log into the SMTP Server prior to sending mail. (Just as you log in to retrieve your mail now, you will now be required to login to send mail.)

This is easily accomplished by going into your account set-up in your POP3 client (Outlook, Outlook Express, Eudora, PocoMail, etc.) and checking "My Server Requires Authentication" under the Outgoing Mail Server information. If an option exists, make sure you check "Use the same settings as my incoming mail server"

If you did not make the changes after December 20, 2001 at 12:01AM CST, you will not be able to send mail. You will receive an SMTP Server Error 550.

Sample Error 550 Message:

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'sample@123m.com'. Subject 'Test', Account: 'sample@123m.com', Server: 'smtp.123m.com', Protocol: SMTP, Server Response: '550 Relaying is prohibited', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79

If you are currently using another ISP's SMTP Server, no changes are necessary.

Your incoming mail will not be affected.
