I can hardly believe it. Unless you're getting a reward for receiving
useless messages, why on earth do you have this record? [ with ruf= ]
I set up my DMARC records in 2012 and have been collecting reports for the
past 13 years. I have gotten 597,000 aggregate reports and 93,000 failure
reports. All of the failure reports take up less than 800MB, an
insignificant amount of disk space these days. A little script puts
summary into info a database which is another 32MB.
The reason I know that failure reports are useless is that I have a
collection from over a decade and the most interesting thing they've
ever told me is who at LinkedIn subscribes to the same mailing lists I do.
R's,
John
