Hi Christoph!

I'm actually not that safe in configuring SpamAssassin, but according to the documentation I read, you can add arbitrary headers using SA on its own by using the add_header Keyword (as of 2.6.x) in its configuration.

You could configure each of your Servers to insert a different header value.

As far as I know, HAProxy is only able to handle SMTP Traffic as raw TCP and can therefore not alter it.
