I think the DKIM setup for the HT list is still not quite right, anyone who knows that in detail please email me off-list. The system is running on an Amazon micro instance running 'Amazon Linux AMI 2017.09' The mailing list is mailman 2.1.29 with outgoing email using postfix and kim-milter The sending server should be putting DKIM-Signature on each message and I'm only seeing ones from google or gmail (depends on routing) Ideas ? -- Rich Roth CEO TnR Global Building the really big sites: http://www.tnrglobal.com Helping move the world: http://www.earththrives.com Small/Soho business in the PV: http://www.hidden-tech.net Places to meet for business: http://www.meetmewhere.com And for relaxation: http://www.welovemuseums.com
