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@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@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 ?
