Re: Sieve seems to break mailbody during automatic redirection

30 Jun 2014

      Hi,
short update.
I found out that with Debian Wheezy I don't have this problem. The problem seems only to be on
Debian squeeze.
I have configured to use "/usr/bin/sendmail".
It seems that there is some problem with the squeeze version of sendmail. The only strange
thing is, that until the upgrade from Dovecot 2.1.15 to 2.2.13 it worked without any problems.
I changed to "submission_host = localhost:25" in 15-lda.conf and now it works correctly. Seems
better than using the sendmail binary.
Many thanks

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
