Hi everyone,

I was having the usual problem today: fresh iRedMail setup, valid SPF, DKIM, DMARC and rDNS, clean IP on blacklists, but still mails went to Gmail spam. IP was clean but I changed it anyway without any other configuration changes and everything works fine.

So Google most likely have some own IP blacklist as well based on previous usage.

Hope this helps someone who's fighting with same issue
