Arrow Notify loop detection logic

The subject starts with (*1) because Fastmail uses this as an email loop indicator for such messages. As I say in this post:
Quote:
(*1) -- This is the loop detector. If you redirect the notification back so that a message forwarding loop is created, the value of this initial text on the subject line will increment to (*2), (*3), (*4), (*5), then the next notification loop will fail (with a warning message sent to your account).
Fastmail has added several tweaks to the notification feature in the past for some users, and it's a mess. The Fastmail staff told me a couple of years ago that they intend to clean up the Sieve modified notify code they use, but this keeps getting delayed, since it doesn't seem very important compared to other needs.
