Kolab 16: Shared Folders do not work (status=bounced)

[Lüttig, Bastian]

Hi Daniel,

I installed Kolab 16 beginning of May on a Debian 8 machine with default 
settings, then installed the updates beginning of June.
After the updates, I encountered the following message when I wanted to 
send messages to the shared folders from outside:
-------------
This is the mail system at host mail.mydomain.example.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

                    The mail system

<"shared+shared/FolderName at mydomain.example"@mail.mydomain.example>: 
mail for
     mail.mydomain.example loops back to myself

Final-Recipient: rfc822; 
"shared+shared/FolderName at mydomain.example"@mail.mydomain.example
Original-Recipient: 
rfc822;"shared+shared/FolderName at mydomain.example"@mail.mydomain.example
Action: failed
Status: 5.4.6
Diagnostic-Code: X-Postfix; mail for mail.mydomain.example loops back to 
myself

--------------
mydomain.example has correct MX records.
mail.mydomain.example is the FQDN of the mailserver

Which looks like, the address has been rewritten including the quotes. 
Is there another setting I need to change? (not acc. your git commit)
Maybe there is another setting in one of the Debian applications?

I tried to find solutions elsewhere, but didn't.

BR
Bastian
