because at 3-5 outgoing emails per week I was obviously sending out to much traffic for your network to handle.

Oh wait, port 25 (SMTP) only works if I connect to YOUR email server for mail?

I just love the way you FAIL TO MENTION THAT PORT 25 TRAFFIC IS BLOCKED TO SERVERS OUTSIDE YOUR NETWORK. Sometimes people use their own mailservers at other locations and only use your services for an IP. But I guess that concept if foreign to you.

... friggin smacktards.

[UPDATE 13:13]
Aparently they have a cryptic opt-out page

and I got this form letter response

Dear SBC Internet Member

Thank you for contacting the SBC Internet Services Security department. Port 25 blocking is based by the SBC Internet Member ID that is used to log on the Internet. We have opted you out of port 25 blocking specifically for the Member ID that you used when you made this request.

Note If you would like any additional sub accounts opted out, please make a request for each Member ID.

This is an automated process and the body of your message will not be read, our system opts out only what is in the Member ID field.

In order for the changes to take effect, you will need to log out of your Internet connection and log back in. If you have a modem, you will have to power off the modem, wait 15 seconds and power it back on again.

Please be advised that the port 25 blocking we have in place, does not stop you from using our mail server. Please refer to our help site at http://help.sbcglobal.net/article.php?item=287 for the email settings to connect to our POP and SMTP servers.
