You made the point.
Isn’t that an argument for why you shouldn’t run your own mail server?
This is false. The dmarc reports from Google do not actually give you the portion of email that is placed in recipients' spam folder.
Do you ever read them? If so, how is daily (!) routine maintenance of your email setup not a massive (well, relatively speaking) headache?
"The dmarc reports from Google do not actually give you the portion of email that is placed in recipients' spam folder."
So it is just about the server and and dns part (the things I as an administrator can control)
Since I configured it in the beginning the reports are all green so I just glance over them. Takes about 10 seconds.
Then again I like to work with infrastructure so your mileage may vary in regard to how much headaches it causes
This is such a canard. I have almost zero problems delivering to anybody from my closet server, and the only thing that has happened in the last several years was getting notices that AT&T was blocking me. I did a quick relay check and emailed postmaster@. It only took a day or two to get an email saying I was clean to them again, and that was without the DNS security extensions you mention.
Maybe cable modem users are held to a different standard? Dynamic IP addresses? I have DSL with static IPs.
