The DMARC policy for MISSEGLE.COM is set to "none":
v=DMARC1;
p=none;
pct=100;
rua=mailto:[email protected];
sp=none;
aspf=r;
If it's set to "p=quarantine" or "p=reject" then that may help
because some systems consider "p=none" to be as useful as not having
a DMARC policy at all.
We use "p=reject" on all of the domains we host eMail for, and what
it means is that forgeries are blocked during the SMTP session with a
5yz (permanent) status code. (Using "p=quarantine" means that forged
messages should still be accepted, but flagged for quarantine, such
as moving into a users "spam" folder.)
Also, if you don't set "sp" then it will default to whatever you set
"p" to (just in case you'd like to simplify things slightly).
