the odd thing is I've been agroups.io member for over a year.? Have had my records setup for protonmail longer than that which required I setup SPF, DKIM and? DMARC.? i am used to seeing 1 or 2 a day.
But suddenly getting over 10 two days in a row is concerning. All mentioning groups.io as the issue.
I did sign up for?dmarcian.com and changed my dmarc to send the reports to them.? I'll see of the next couple of days how they get interpreted..
