FAQ:

Why would I want to use Sieve/WebSieve when I can set up filters on my local client?

Answer:

Sieve/Websieve allows you to set up filters before your email is delivered to you; saving bandwidth and providing a consistent view no matter where you read your email. Sieve/Websieve provides the most functionality to IMAP clients because the rules do not apply to your local folders, only folders which reside on the server.

Since POP does not allow you to create folders on the server, this limits the usefulness when used in this environment. Websieve may still be used for setting a vacation message, automatically deleting mail (not recommended), and forwarding your mail to another address. However, you will still need to create filters on your local client as long as you use POP3 protocol.

For example, if you create your “rules” on your workstation to place unwanted messages in a folder called “junk” and then decide to check your email from home or through the web interface, the email won’t reside in the “junk” folder on your home machine. If you set up your “rules” through Sieve you only have to create your modifications in one place for consistency across clients and locations.
