Fresh Install: DKIM And DMARC

Post by cbritton1978 »

I am new to using eFA. I noticed I was getting items in quarantine for double file extensions. It looks like the gateway is trying to send out a DMARC report. I disabled DKIM and DMARC, however, after I did that I stopped receiving emails. As soon as I enabled the feature again I started getting emails. Is this normal? Is it a spam check feature or just a reporting feature or both?

Will eFa send the DMARC report itself? If it does wouldn't the the DKIM key need to be changed to match the key on the email server?
