Hi,
I'm having troubles lately with a Sieve script of mine:
require "fileinto"; require "mailbox"; require "regex";
if header :regex "Subject" "\\[.*PATCH.*\\]" { fileinto :create "Inbox.Patches"; }
This should move all patches with "[PATCH]" or "[RFC PATCH v3]" into this Inbox subfolder, I'm pretty sure this version worked flawlessly in the past but since a couple of weeks ago it's not working with some emails.
Debugging this, with manually editing mail files, I came to this discovery. That one mail matches and it's getting moved to the correct folder:
Subject: Re: [PATCH v2 3/6] arm64: dts: qcom: qcm6490-shift-otter: A
Adding one more character leads to it not getting moved:
Subject: Re: [PATCH v2 3/6] arm64: dts: qcom: qcm6490-shift-otter: Ad
Does anybody have an explanation for this why this broke, and how to fix either Dovecot/Pigeonhole or my Sieve script?
I've already lost hours trying to figure this out and I'm not getting any wiser...
Thanks, it was a bug in the new pcre2 code. Fix in the next version / https://github.com/dovecot/core/commit/d96c98e08ca0d445bd46192829685fbeaf401... & https://github.com/dovecot/core/commit/e704d9c72850684c1b82011c9550adbd4200f...
