Hi there I'm trying to move all mail that contains "*EXT*" in the "Delivered-To" header into a folder "EXT". I use postfix/dovecot and I added this custom rule: Code: if header :regex ["Delivered-To"] [".*EXT"] { fileinto "EXT"; stop; } The problem is, that it's not being put into the EXT folder but stays in the main inbox. So, what's wrong with it? Or is there a way to get some logs on this?
