Ask HN: Any improvement in Gmail's treatment of small servers in the past year?
I'm wondering whether any of you have seen any improvements on this front in the past year. Are there any new introspection tools to diagnose deliverability problems when they happen? New guidelines which verifiably reduce the probability of such problems occurring?
As an administrator of a small email server (with SPF/DKIM/DMARC/MTA-STS set up properly and a clean reputation of 5+ years), from my point of view nothing has changed, except perhaps for the worse. Email sent to Gmail users seems to end up in the Spam folder more often than before.
