Hello,
(Please CC me on any replies since I'm not subscribed to this mailing
list.)
I'm writing to report a bug that I just ran into, involving
Sieve/Pigeonhole message redirections. I recently added a rule
involving redirections and the redirected messages were getting
corrupted. I traced the issue down to the fact that an Mbox-style
"From " header line was getting intermixed with the message headers --
note the entry between the two "Received:" headers in this example,
which shows the text being delivered to the MTA on stdin:
X-Sieve: Pigeonhole Sieve 0.4.24 (124e06aa)

This was happening with trivial test messages, and trivial Sieve rules,
but I can provide specifics if they would be helpful.
Versions: CentOS 7.9.2009; Dovecot 2.2.36; Pigeonhole 0.4.24; Exim
4.92.2.
Below I've added the output of `dovecot -n`. My `sendmail_path` setting
was empty before, but as a workaround I've set it to a wrapper script
that strips out everything before the `From `, "solving" the problem.
Thanks so much for building Dovecot, I've been using it with great
success for more than a decade!
Best,
Peter
