Rules syntax

[anantone]

Hi, I was really happy to find this, but I can't manage to get any rules match, even though the IMAP connection is working fine and I see the incoming emails being matched for rules. Even using only
[rules]
[rules.default]
subject = "test"
and sending an email with subject "test", I don't get a match.
Could you please explain basic rules syntax?
Is there a way to set up a rule to get a notification for EVERY email received in the connected mailbox?
Thanks a lot!!
