I am wondering if you are doing final delivery from your own systems, or sending it through panix.com? Or maybe you are using a different sender domain. I ask because your current email does seem to go through panix.com and has a DKIM signature (although it seems to be invalid). But if you are NOT sending through panix, or you are using a domain that does not have SPF and/or DKIM records, this could explain this completely; my understanding is that most large email services consider email without some combination of SPF/DKIM/DMARC to be very likely spam, and this plus multiple recipients would nudge this into being considered spam. >I'm looking for suggestions (within or outside NMH) for steps 2a & 3 of >the proposed workflow: >[...] It looks like you could do 2a/3 with a combination of a postproc, using "scan" with a custom format to extract out the various headers, and "anno" to alter those headers. --Ken
