Hi Dear Community Friends, it is few days now, i am trying to figure out why DKIM is working / not working. Any assistance would be very much appreciable. Server IP is not blacklisted ever, MX, PTR SPF, DKIM records are available in DNS. why it is working at Gmail, why failing at Yahoo? Gmail dkim=pass header.i=@digital-infotech.net Yahoo: domainkeys=neutral (no sig); from=digital-infotech.net; dkim=permerror (future timestamp) Prabh S. Mavi
