Stricter Email protocols are being required such as DMARC for Microsoft, Yahoo and Google

I looks like that Microsoft, Yahoo and Google will now require the following for servers that send more than 5000 emails to their servers.

  • SPF or DKIM
  • DMARC set to at least none
  • FCrDNS (I think this is a term to include both DNS and rDNS)

My Thoughts

  • The 5000 limit will not stand for long because spammers can count.
  • It seems DMARC will be required so you might aswell have both SPF and DKIM enabled.
  • DNSSEC will be next for domains.
  • Other emails providers will follow suit.

Since we installed our iredmail We have had DKIM DMARC, and SPF active. It is the only way to not risk to end up in spamfolders. Its easy to implement and a one way thing. You can use 1 DKIM for multiple domains but our experience is that it is a bad way, the risk of being considered as spam is much bigger

Anyone not having all those setup already and are running a legit email server, deserve to remain in queue for eternity.
But who am I kidding.
Way too many firms buy the cheapest hosting they can find, just create some email acocunts and call it a day. Nothing secured or compliant.
Then, when their emails get bounced, come up with the old “but we only have this problem with your email server. Everyone else accepts our emails”
