This is an old revision of the document!

Sieve mail filtering language was inspired by (and hopefully lessons were learned) from the Flames filtering language.

The history of Sieve language is described below:

This meeting started out as an informal discussion of anti-spamming techniques, and the need for a distinct, standardized language for server-side filtering was discussed. The conclusion was that this should be pursued as a separate activity. Participants of the November IMAP meeting not also at this meeting were notified of this by private mail.</td> </tr> <tr>   <td valign="top">January 11, 1997</td><td valign="top">mta-filters mailing list established at Internet Mail Consortium; first posting.</td> </tr> <tr>   <td valign="top">January 15, 1997</td><td valign="top">Strawman taken on mta-filters mailing list to establish continued interest in standardization.</td> </tr> <tr>   <td valign="top">March 24, 1997</td><td valign="top">First International ACAP Meeting held in Pittsburgh, PA.
