GreenAnt uses an advanced filtering system based on [sieve](

This mail filtering happens before the mail is deleivered and allows powerful functions including:

  • auto-deliver to a mailbox
  • adjust SPAM thresholds
  • auto-forward
  • auto-respond and vacation messages
  • multiple cascading rules

The easiest way to edit your filters is via the webmail interface.

In Settings there is a Menu called Filters. You can edit your filters in this menu.

A valid filter requires:

  • Filter Name
  • A Condition to match
  • An Action to carry out

Filters will be run in the order they are listed. Sometimes this order will matter as you can Keep scanning after a filter matches (the default) or choose to stop when a filter matches.
