Good Morning,

a brief update...

Information Systems will delay the implementation of access control 
outlined below on outbound e-mail scheduled for today.  This delay 
will allow us more time to work with a few Departments and ensure 
"direct delivery" of their e-mail avoiding any significant 
disruptions.  We hope to implement this additional restriction before 
week's end.  Another brief update will follow prior to implementing 
this access control.

Last week, we saw a steady increase in outbound authenticated e-mail 
(SMTP authentication).  Thank-you!

As a reminder, IS will continue to promote SMTP authentication 
throughout the month focusing on particular e-mail client 
configurations each week.  Eudora remains our focus this week. 
Colleagues who use Eudora as their e-mail client are encouraged to 
plan an upgrade to Eudora v 5.2.  This version of Eudora supports 
SMTP authentication.  MIT's Eudora installers, available at 
<http://web.mit.edu/software/>, are pre-configured for SMTP 
authentication and encryption.

In closing, our thanks to our IT colleagues for their support and 
assistance as we implement these additional measures to limit our MIT 
Mail System to our Community.  Thank-you for sharing this information 
within your Departments.  Should you have any pressing questions or 
concerns, please feel free to contact me.

Regards,
Theresa

>Information Systems (IS) writes to share several important

>Commencing Monday, November 3rd, IS will enable another level of 
>access control on outgoing e-mail.  This additional level of 
>restriction is an interim measure as we move closer to requiring 
>SMTP authentication for all outgoing mail submissions.  All outgoing 
>e-mail will have its  "From: address" checked to ensure a valid 
>username or e-mail list is being used for mail submission.  Messages 
>from invalid addressees will not be accepted.

>SMTP Authentication
>-----------------------------
>Network Operations modified the outgoing mail server, 
>outgoing.mit.edu, to ensure the reliable delivery of authenticated 
>mail over unauthenticated mail. This ensures authenticated mail is 
>not affected by the "blacklists" negatively impacting e-mail 
>delivery from MIT to remote sites, and the authentication 
>requirement should ensure it remains exempted from the various 
>"blacklists".  Throughout November, IS will be providing regular 
>updates on the broad range of e-mail clients (Outlook, AppleMail, 
>etc.) in use within the MIT community and the proper SMTP 
>configuration, to take advantage of SMTP authentication.
>
>Today, we will focus on Eudora.  Eudora 5.2 clients running on 
>Windows, MacOS9 and MacOSX have the appropriate software support for 
>SMTP authentication functionality.  MIT's Eudora installers, 
>available at <http://web.mit.edu/software/>, are pre-configured for 
>SMTP authentication and encryption.  We wish to encourage the 
>Community, who use Eudora as their e-mail client, to upgrade.
>
>Colleagues familiar with reviewing e-mail headers will note the 
>following entry on e-mail which has been sent via SMTP 
>authentication:
>
>User authenticated as xxxxxxxx at ATHENA.MIT.EDU) by 
>melbourne-city-street.mit.edu (8.12.4/8.12.4) with ESMTP id 
>h9RN4RhV029598 (version=TLSv1/SSLv3 cipher=RC4-SHA bits=128 
>verify=NOT) for <xxxxxxxx at mit.edu>; Mon, 27 Oct 2003 18:04:27 -0500

>In closing, IS thanks the Community for all of its support and 
>patience as we implement appropriate measures to ensure the highest
