Subject: *** ACTION: IP Address of Outbound SMTP Server Requested (Updated 10/21/03)

AT&T Business Partners & Customers

AT&T has received many of the requested IP addresses in response to an
e-mail originally broadcast yesterday to our business partners and
clients. However, we have also received many concerned responses to
the original request.

This 2nd e-mail is to let you know that this is a legitimate AT&T
request asking for your cooperation, which will let us improve the
service that AT&T offers you and that our partnership requires. We
have provided a toll-free number below to help you confirm the
legitimacy of this request.

We have assembled the distribution list for this e-mail by looking up
the administrative contacts for each of the known e-mail domains we
currently exchange e-mail with, referencing WHOIS and other such
services available via the Internet.

What AT&T is asking is for you to help AT&T to restrict incoming mail
to just our known and trusted sources (e.g., business partners, clients
and customers). Therefore, we need to know which IP address(es) are
used by your outbound e-mail service so we can selectively permit them.
Please send this information to the following e-mail address

If you need assistance determining what these IP addresses are, please
contact your company's administrative e-mail server support / network
administration personnel. We regret that AT&T is burdening you with
this request, but our AT&T security team is advising that we take this
step to help safeguard our e-mail systems, which ultimately will help
us serve you better.

Please contact us with any concerns or questions:
AT&T Security Help Desk 1-800-456-4230, prompt 4 (8am - 10pm est)

Thank you for your prompt attention to this matter. We appreciate your

Brian Williams, IP Network Services
Tim Scholl - District Manager, IP Network Services
Kevin O'Connell - Division Manager, Information Technology Services
Bill O'Hern - Division Manager, Network Security

AT&T has an urgent situation with our anti-spam list. In order to
continue to allow email to AT&T you need to provide the IP addresses of
all your outbound email gateways. If you do not respond immediately,
your access may not continue. The required information should be sent
