Sieve seems to break mailbody during automatic redirection

30 Jun 2014

      Hi,
I have a strange problem with sieve.
After upgrading to 2.2.13 sieve seems to break the mailbody during automatic redirection.
I have the following configuration.

User A sends mail to User B.
User B has an automatic redirect to User C
User C geht the mailbody broken

I did some debugging.
This is a part of the mailbody which i grabbed from the mailqueue before the mail gets delivered to user B:

Looks normal to me.
Now:
This is the part of the mailbody which i grabbed from the mailqueue after user B has received the mail and sieve has injectd
it to the mailqueue for delivering to user C.

The part of the mail-header looks normal.
But as you can see at beginning of the mailbody something inserts the strange character "^M"
after each newline. According to Google this is a endline charachter from Windows. And this
seems to break some clients (Eg. Lotus Notes).
With dovecot version 2.1.x I don't have this problem.
Have you any solution for me?
Many thanks
