SRS rewriting fixed & simplified

Hi,

When checking the mail setup to figure out what we can do to get ARC signing working (both for forwarded as well as for mailing list mail), I found from my testing that SRS rewriting wasn't working anymore.

I have changed and simplified the mail system setup: it's now using the built-in SRS in Exim and instead of very complex setup with an external daemon, I was able to copy (almost verbatim) the example setup from the Exim manuals to make it work.

This, however, doesn't solve the ARC signing problem.

Hopefully at least *some* of our setup starts working better again.

My next thought is to enable ARC signing in mailman3, because at least that will fix mailing list traffic handling, if nothing else.

Other ideas?

Regards,

Erik.
