= What is Sieve filtering? =
At a basic level, Sieve is a system whereby the server is given rules by you to process incoming email - e.g. forward emails, discard emails, or filter your email into folders. It then means that, whatever email program you use, your email is already filed away in to their correct folder according to your needs.
It is helpful if you:
*Read email from a number of devices

*Maximum number of actions = 128
== Creating Sieve Filters ==
=Other Sieve Notes=
*When using fileinto: with :create, a new folder will be created if it does not already exist, this is normal. In this case, the new folder will be subscribed to automatically. -You may need to restart your client, or collapse and reopen the folder list (e.g. Thunderbird), for it to notice that there is a new folder that should be listed.
*spam folder: If you have a folder called 'spam' then email which is marked as spam will end up there bypassing any Sieve filters. If you do not wish to happen then rename or delete the folder called 'spam', and add a filter to move spam marked messages to another folder (e.g. junk, rubbish, etc.) '''Update November 2023''': this
require ["fileinto","mailbox"];
if exists "X-Spam-Flag" {
if header :is "X-Spam-Flag" "YES" {
if exists "X-Spam-Bar" {
# 20 OR MORE +
if header :contains "X-Spam-Bar" "++++++++++++++++++++" {
# Can't reject, not supported
fileinto :create "bad-spam";
stop;
}
}
fileinto :create "spam";
stop;
}
}
