Hopefully that call to SBC will take care of it. Below is a document from
their online help desk. I filled out the abuse of service form and they
should remove the filter and all should be back to normal. I hope....

Sure would have been nice if SBC had told us.....

I'll look into the different error message my boss is getting with your
instructions but I think that will clear up too with SBC lifting the filter.
Thanks SO MUCH for your help - invaluable!

And I hope this helps someone else - call your ISP and see if they blocked
port 25!
 

SBC Internet Services (SBCIS) is taking positive steps to help combat junk
email and spam. In addition to network upgrades, free spam filtering and
anti-virus software, SBC is implementing outbound SMTP port controls to
ensure the SBC network is as reliable as possible for our Members.

SBCIS began filtering Port 25 to separate outbound SMTP mail from dynamic IP
mail. Most SBCIS Members already use SBCIS or Yahoo! SMTP mail servers for
outbound email and will not be impacted by this filter.

Members not using Web mail access or SBC mail servers, such as a private
company or university mail server, will not be able to send outbound email
until one of the following actions are taken:

1. Convert your outgoing mail to the SBC mail servers.
2. Contact your server administrator for information about alternate access
methods allowing connectivity to the 3rd party mail server (i.e., VPN, Web
mail or Outlook Web Access).
3. Request that SBC removes the SMTP port filter from your account: on our
Abuse of Service form, enter the details of your request in the Abuse
Description field.
