Hi David,

thank you for this info. It is indeed a help. I have previously received 
very contradictory information on this subject from other sources. I 
have already configured Mailman correctly according to the instructions 
you recommended, but I was not aware of the option to remove the DKIM 
header. If the DKIM header can be removed, I think that the prefix [Cin] 
and the footer can be reactivated, because the original DKIM is removed. 
So my understanding is, if I'm wrong, please let me know. We are trying 
this option and I will follow the next days how Mailman behaves. Thanks 
again for the tip.

Since I found a way to solve the problem with DKIM, I have activated the 
prefix and footer. We will see how Mailman and Gmail will behave with 
these settings.
