Change in Default Greylisting Behavior

As part of our ongoing efforts to improve the reliability and usability of our e-mail infrastructure, on January 15, 2009, SCS Computing Facilities will make the following change to the default greylisting settings for all SCS Computing Facilities mail users. Change the "not set" behavior from "disabled" to "enabled". What this means is that people who have neither enabled nor disabled greylisting will have greylisting activated.

Greylisting is a supplement to the existing Sophos anti-spam service. In conjunction with Sophos, greylisting has been shown to greatly reduce the amount of spam that reaches a user's INBOX.

Users can enable greylisting immediately for themselves, by visiting the Corvid Attribute page:

https://www.fac.cs.cmu.edu/corvid/lookup

...and setting the Full Grey Listing attribute to true.

If you have any questions about greylisting or if you are uncomfortable making this change, please contact the SCS Help Desk and they will enable this feature for you.

For more information on greylisting, please see:

Please contact the SCS Help Desk at x8-4231 or send mail to help@cs.cmu.edu with any questions or concerns regarding Greylisting.

Thank you for your attention,

SCS Help Desk
