dovecot - Sep 2018 - Problem with envelope from in Pigeonhole after upgrade

On our FreeBSD 11.2 servers, we recently upgraded from:

dovecot2-2.2.26.0_1
dovecot-pigeonhole-0.4.16_1

to:

dovecot-2.3.2.1
dovecot-pigeonhole-0.5.2_3

Prior to the upgrade the envelope sender was as expected.

After the upgrade, the envelope sender for a user with a sieve script
configured is now being set to:
>From MAILER-DAEMON  Tue Sep 04 13:31:39 2018
The same user without a sieve script in place gets:
>From someone at gmail.com  Tue Sep 04 11:06:04 2018
This happens when manually testing by directly executing:

/usr/local/libexec/dovecot/dovecot-lda -d dgdtst -f someone at gmail.com

It happens with an empty sieve script i.e. just using the implicit keep
functionality.

I have groped around looking for a configuration setting that might fix the
behaviour but nothing I have tried helps.

Can anyone suggest what to set to correct the problem ?

To get out of the problem this bug was causing I have now downgraded the
affectect servers to using dovecot 2.2.36 & dovecot-pigeonhole 0.4.24 .

These versions work correctly for me.

Has anyone else been able to see the same sort of problem when using dovecot-2.3
and dovecot-pigeonhole-0.5 ?

I am wondering if this is a FreeBSD porting issue or a general problem.

Hi!

How are you executing dovecot-lda? I can get 'MAILER-DAEMON' if I omit
-f sender-address-here parameter.
