Sieve filter to get rid of itch.io game updates

!itch_sieve.md

If like me you have used a script to claim all of the itch.io games in a bundle then you are also receiving an unholy amount of E-Mail spam.

I have made this sieve script to get rid of all the game news (well, mark them as seen and put them into a folder). This puts the mails in the "itch.io" folder by default but nothing keeps you from chaning that.

itch.sieve

require ["imap4flags", "fileinto", "body"];

if address "From" "postmaster@itch.io" {
        if body :contains "receiving this message because you purchased or own" {
                addflag "\\Seen";
        }

        fileinto "itch.io";
}
