I did another test with dovecot-lda instead of lmtp:

dovecot 2.2.10, dovcot-lda and pigeonhole-0.4.2
--> Message is forwarded and fully readable.
dovecot 2.2.10, lmtp and pigeonhole-0.4.2
--> forwarded message is broken
If I compare both messages I see trailing blanks like

...
Subject: anhang pdf
Content-Type: multipart/mixed;    without trailing blank
...
X-ENVELOPE-TO: <me at other.domain>
blank line here
--> and now every line until the end of the message has one trailing 
blank, starting with:
This is a multi-part message in MIME format.

This should be the reason I think.
