I'm sorry that this is off subject and do not have anything thing to do 
with sendmail specifically, but more of a general question as I have 
noticed that I do not get mail from all domains, looking at the firewall 
logs, I can say the remote side do not even try to connect to the server.

I have done all I know of, SPF, DMARC, DKIM, but is there something new 
that is required nowadays?
