Modifying your email filters using sieveshell

If you need to modify your Sieve email filters by hand rather than using the tools on the ONID web site, see the instructions below.
ONID email filtering rules use the Sieve language, which was designed specifically for email filtering. The Sieve language is formally defined in RFC 3028. There are many example Sieve filters that you can use as a starting point to learning the Sieve language. You can also look at the rules created by the tools on the ONID web site.
To begin, you'll need to SSH? to shell.onid.oregonstate.edu. Then execute sieveshell, specify the ONID mail server, and authenticate with your ONID password:
username@shell:~$ sieveshell imap.onid.oregonstate.edu connecting to imap.onid.oregonstate.edu Please enter your password: >
At the "> " prompt, you can type "help" to see a list of available commands:
> help Usage: sieveshell [-u username] [-a authname] [-r realm] <server> help - this screen list - list scripts on server put <filename> [<target name>] - upload script to server get <name> [<filename>] - get script. if no filename display to stdout delete <name> - delete script. activate <name> - set a script as the active script deactivate - deactivate all scripts quit - quit
Use the "list" command to view the Sieve scripts you have stored on the server, as well as which script is active.
> list onid-web <- active script
To save a script out into a file so that you can edit it, use the "get" command.
> get onid-web sieve.txt
After you have edited sieve.txt, use the "put" command to upload it.
> put sieve.txt onid-web
Note: If your Sieve script had errors in it, sieveshell will tell you the errors and not allow you upload the script.
The final step is marking your script as active, using the "activate" command.
> activate onid-web
Use the "quit" command to exit sieveshell when you are finished making changes.
