So it +is+ obvious from the documentation. Just not the part I read. ;-)
But now I'm getting a glimpse of an answer.
RIght now, I'm failing ARC/DMARC with either a DKIM header from the first
pass through our SMTP servers, a DKIM header from the pass through the
LISTSERV server, or both. That's three cases (four if you include the
trivially failing case with neither header). So my next step, I think, is
to add a DKIM header for the second pass through our SMTP servers.
That's three DKIM headers. Typically there's just one, right? Should I
begin by suppressing all the headers but the last one and see if that
passes? I'm willing to experiment and find out.
