i've got one that i did some searching for here but likely not enough to find the cause. I have a few customers on my server and when they send emails from their outlook or phone the responses go to the spam folder of those who they have responded to.
I did encounter this one time on my server prior to migration but it was an odd duck and never appeared on a routine basis.
Do you have any idea's what it could be that could resolve this issue? Could the root cause of this be because we don't have a DKIM & DMARC on this domain name? If so I will work to get one in there.
Attached is the data from outlook for the headers.
