DMARC setup

Hi,

Could someone explain to me how we setup DMARC on the servers? We have DKIM and SPF working, but I can't for the life of me figure out the DMARC stuff.

Thanks!

Andy

Hi

You should be able to use a DMARC genarator.

Take the out from it and amend the DMARC filed in the DNS section. Just make sure to keep the rules relaxed untill you know your OK.

Thanks. Yeah I did a bit of research, and found that just adding:

_dmarc v=DMARC1; p=reject; sp=none; rf=afrf; pct=100; ri=86400

Did the job :) For some reason I was thinking it was much harder than that!

Cheers

Whats not working? Adding a TXT record of "_dmarc", with the value "v=DMARC1; p=reject; sp=none; rf=afrf; pct=100; ri=86400" ?

Glad to help :) I've also gone one step further and started using: https://glockapps.com . This lets you keep track of DMARC hits / failures, mis-configurations etc. Worth the money for me for the peace of mind :)

I have added below DMARC record and it worked for me.

Code: Select all

v=DMARC1;p=reject;pct=100;rua=mailto:[email protected]
