Dear all,
I have already experienced Google ratelimiting DMARC reports every now and
then, which may be OK if they want it like that.. but this is new (to me):
[snip]
Diagnostic-Code: smtp; 550-5.7.1 [65.108.69.105 12] Our system has
detected that this message is 550-5.7.1 likely unsolicited mail. To reduce
the amount of spam sent to Gmail, 550-5.7.1 this message has been blocked.
Please visit 550-5.7.1
https://support.google.com/mail/?p=UnsolicitedMessageError 550 5.7.1 for
more information. e21si14404251ljg.437 - gsmtp
I guess there's nothing to do, but I find this irritating.. I mean, they
could just stop requesting DMARC reports instead of requesting and refusing
them? :)
What makes you believe they reject the content of your message and not your
mail systems regardless of what it sends?
So far I've never had e-mails rejected by Google, including DMARC reports (which
could be treated differently than other e-mails).
So my assumption is that something in the content triggered the rejection.
Maybe if they check for bad IPs or domain names *within the content/body* (like
many spam filters do unless instructed otherwise) then a DMARC report (or daily
server logs, or messages in this list including spammer IPs, etc.) should be
exempted from that, as otherwise these e-mails cannot achieve their very purpose
of reporting such things.
But anyway.. just sayin', in case Google may want to do something about this.
Cheers,
Bernardo
