This is clearly a strange thing, im not connected by any way to google
The only fact is that i still have a google account but i deleted completely the gmail apps, replacing it with my personal e-mail address in the google account (so you can delete your gmail, keep your google account and put another mail inside) because i still need my google account for something else
it doesn’t seems malicious but i don’t know why i’m receiving that now
Two cosiderations … the number of emails you have sent and to whom they have been sent.
This is similar to DMARC reporting. A DMARC report is only generated on a day that there are emails sent to the provider doing the reporting. Also there are only a few providers participating in DMARC reporting. So far I have only received DMARC reports from Google, Verizon (Yahoo!) and FastMail. I expect participation in MTA-STS to even be less.
considering the low participation, do you think I should enable MTA-STS? as currently I have not configured it yet and I’m still not sure if I should… from what I understand, if I enforce MTA-STS, any server trying to mail me that does not have MTA-STS enabled will be unable to mail me? been reading this explanation here
Don’t be fooled by this IP, it is “owned” by google, but it’s just an IP that anyone can spin up a virtual machine or other google services and use for good or bad. This IP has a bad reputation on 18 sites that track spam/malware:
