[FIXED] How can I fix the problem with Gmail? Gmail marked email with passed SPF, DKIM and DMARC as spam

Issue

Gmail moves messages to spam folder. PTR records for ipv4 and ipv6 are available. I have the headers: SPF: PASS с IP-адресом 2a05:480:0:992f:0:0:0:2. DKIM: 'PASS', domain drom.com.ua DMARC: 'PASS'

Where can be the problem? Thanks

Solution

Unfortunately this seems to be business as usual with gmail. Their spam filter seems entirely arbitrary and uncontrollable by recipients - for example adding addresses to your address book, marking messages as "not spam", or repeatedly moving messages from spam to your inbox does not help, and nor does following their guidelines, which include implementing measures such as SPF, DKIM and DMARC, just as you've done. On my own gmail account, I often find messages sent to myself end up in spam!

Their postmaster tools are also broken - this is supposed to provide a feedback mechanism that allows server admins to see why IPs or domains are being blocked or spam filtered, however, it doesn't work properly, and it's very common to see domains & IPs marked as "bad" despite having zero spam reports. There is also no support available for postmaster tools, so you can't even report such problems. It might be worth trying anyway just see what they think of you.

In short, you are entirely at google's mercy - even if you're doing everything that they ask, your messages may still get spam filtered, and you have no recourse.
