<div>Good Morning,</div>
<div><br></div>
<div>a brief update...</div>
<div><br></div>
<div>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.</div>
<div><br></div>
<div>Last week, we saw a steady increase in outbound authenticated
e-mail (SMTP authentication). Thank-you! </div>
<div><br></div>
<div>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. </div>
<div><br></div>
<div>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.</div>
<div><br></div>
<div>Regards,</div>
<div>Theresa</div>

<blockquote type="cite" cite>Information Systems (IS) writes to share
several important developments with the MIT Mail system. MIT continues
to encounter challenges with e-mail delivery to several large e-mail
providers (ISPs, AOLs, AT&T, etc.) These recent developments
are in a continued effort to ensure the highest quality e-mail
services for our Community.</blockquote>
<blockquote type="cite" cite><br></blockquote>
<blockquote type="cite" cite>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.</blockquote>

<blockquote type="cite" cite>Please help us share this recent
development among your colleagues. Monday, November 3rd is
quickly approaching!</blockquote>

<blockquote type="cite" cite>SMTP Authentication</blockquote>
<blockquote type="cite"
cite>-----------------------------</blockquote>
<blockquote type="cite" cite>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.</blockquote>
<blockquote type="cite" cite><br></blockquote>
<blockquote type="cite" cite>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.</blockquote>
