WebSieve Sieve Script editor released

An integral part of the Corvid mail system is filtering at the server; Corvid uses the Sieve filtering language to accomplish this. In our environment Sieve is generally used to filter SPAM and set vacation messages. One supported tool for creating and managing sieve scripts on Corvid is AvelSieve, part of the SCS webmail client.

Our users have told us:

  • The AvelSieve tool has been known to generate broken scripts
  • We have received requests for a simple interface to common  filtering tasks (filtering SPAM, enabling vacation messages)
  • We have received requests for a better way to directly edit  scripts on the server

To that end, we have deployed WebSieve:

We have found WebSieve to be both more predictable and more secure. We will be working to improve the feature set, and welcome requests for additions to the set of pre-scripted common tasks. We invite you to take a look, and let us know what you think. If the community feedback is positive, we are planning to retire the AvelSieve interface in mid-July of this year.

For more on WebSieve and using Sieve with Corvid, please see:

Thank you for your attention,
