I use SBC Global/Yahoo DSL, I can't send mail.

    SBC/Yahoo has made the choice in Texas to start filtering the mail port 25. Basically, all mail traffic on your DSL connection is monitored and any traffic that is outbound (SMTP) mail that is NOT destined to be delivered by their servers, is being blocked (rejected).

    This is generally done when an ISP can not adequately control their spam problem, their users get infected and their PC's start sending out large amounts of mail to other people without the owner's knowledge (what Viruses and Trojans do) and getting SBC in trouble with spam watching systems that then blacklist their network IP addresses. This helps curb that problem, but it creats another by hampering the innocent users, and in particular the corporate sector. In short, your freedom of choice has been removed without your knowledge or warning (2/23/2005).

    This means that if you have been using Authenticated sending, where your Outgoing Mail Server (SMTP) is the same as your Incoming (POP3) Mail Server, with Authentication turned on (IE "my server requires authentication" checked in your mail options) - you can no longer do this. You must change your mail settings to one of the following outgoing mail servers (and turn OFF authentication):

    1. mail.sbcglobal.net (Recommended Choice)
    2. mail.swbell.net
    3. smtp.sbcglobal.yahoo.com

    The good news is that SBC is allowing it's users to fill out a website form requesting that they remove this feature on their account. The following method will allow you to "opt out" of this forced filtering:

    1. Go to : http://help.sbcglobal.net/servabuse.php
    2. Fill out all of your information as required.
    3. When it asks for "abuse type", choose 'Opt out port 25'.
    4. In the Abuse Description portion of the form, you need to enter in your domain name (IE mail.mydomain.com where mydomain.com is your actual domain name)

    This procedure typically takes 24 hours for them to complete, and will allow you to resume authentication sending.

    If you are frustrated with this forced restricted change on your Internet connection, we politely suggest that you contact your SBC representative, and let them know that you are not happy with this forced blocking and that having no notification on this change, which caused an inconvenience, was very unappreciated.
