Secure outbound e-mail at MIT

Secure outbound e-mail at MIT

MIT has been working to stop the misuse by spammers of its outgoing e-mail server, which routes messages to other mail servers on the Internet. MIT's "" server has been modified to take advantage of secure SMTP (Simple Mail Transfer Protocol). SMTP authentication helps to ensure that mail is sent only by authorized users. Adopting secure SMTP helps to allay concerns of Internet service providers (ISPs) who may block mail when they find that outgoing mail servers are being used as spam relays.

Information Services and Technology (IS&T) encourages all MIT community members to configure their e-mail software settings for secure SMTP authentication. For instructions on how to securely authenticate your outbound e-mail at MIT, go to

High-performance computing

The Computationally Intensive Computing (CIC) team was formed to identify ways to support faculty and research staff doing high-performance computing. Its recommendations address CIC services in communications, education, research and infrastructure support. IS&T has established the CIC Community of Practice web site at, open to anyone with an MIT network account and certificate. If you have ideas about the CIC initiative, contact Phil Long at or Pat Dreher at
