[Dovecot] forwarded message is broken in 2.2.10 with pigeonhole-0.4.2
Hi,
forwarding a message with sieve like
redirect:copy "me at other.domain";
was working without any problem until dovecot-2.1.17, dovecots lmtp and
dovecot-2.1-pigeonhole-0.3.5.
Using dovecot-2.2.10 , dovecots lmtp and dovecot-2.2-pigeonhole-0.4.2
the structure of a forwarded message is broken. Content of a message is
not displayed or an attachment (for instance pdf) can not be opened by
(different) clients. Writing a html mail or plain one makes no different.
I have compared two messages and the main different is a missing
Content-Type: multipart/alternative;
boundary="...."
to encapsulate the body of the forwarded message. Was it lost in sieve?
Here parts of a "well" forwarded message:

Was it lost in sieve?Hello Burckhard, Just to be sure. Above excerpt and your two sample messages invariably show "boundary=" items starting at the beginning of a new line. Is this really the case?
