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.
