Hi, forwarding a message with sieve like
redirect:copy "me@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:
