Yes, definitely, Harakiri. I already found out. I started to implement
a parsing and signing feature with a filtering script, which works in
very simple cases, but fails in any of the more complex ones.

Since we will not want to buy anything, I guess the DKIM suggested by
the others will be the way to go.

Thank you for your answer.
