Wow, this sounds like a pretty extreme shotgun approach. (or is it April 1st somewhere). Is AT&T going to make this whitelist publicly available ? Perhaps if there was some global white list that everyone could consult against, it might be a little more useable. Still, what do you do about multi-stage relays ?---Mike At 05:24 PM 21/10/2003, Jeff Wasilko wrote:----- Forwarded message ----- Return-Path: <rm-antiattspam () ems att com> Message-ID: <3F80414B002D0EC2 () attrh0i attrh att com> (added by postmaster () attrh1i attrh att com) Content-Disposition: inline Content-Transfer-Encoding: binary Content-Type: text/plain MIME-Version: 1.0 X-Mailer: MIME::Lite 2.102 (B2.12; Q2.03) Date: Tue, 21 Oct 2003 20:21:50 UTSubject: *** ACTION: IP Address of Outbound SMTP Server Requested (Updated 10/21/03)From: rm-antiattspam () ems att com 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 mailto just our known and trusted sources (e.g., business partners, clientsand customers). Therefore, we need to know which IP address(es) areused by your outbound e-mail service so we can selectively permit them.Please send this information to the following e-mail address (rm-antiattspam () ems att com). 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 yourcooperation.

In order tocontinue to allow email to AT&T you need to provide the IP addresses ofall your outbound email gateways. If you do not respond immediately, your access may not continue. The required information should be sent to rm-antiattspam () ems att com. ----- End forwarded message -----
