Some correspondents have kolab_user at kolab_server instead of From address in their replies [Solved]

[Johannes Ranke]

Hi again,

I could solve this problem by setting the option

[kolab_smtp_access_policy]
...
sender_header_enc_key = xxxxx

in my /etc/kolab/kolab.conf. This has the effect of suppressing the addition of 
the Sender: header, which showed kolab_user in my case. Instead, the encrypted 
sender is added as an X-Authenticated-As: header, which is fine with me because 
it will most likely not be used by my correspondents email programs as a 
reply-to address.

Apparently other people had trouble with these headers as well, which lead to 
this task

Cheers,

Johannes
