Funny. I'm somewhat new to the game but my email server has had very few problems delivering anywhere (hosting a small business' email, and personal email for the employees.) I've got spf, dkim, and dmarc. I use tls on everything. Got a static ip (linode) with rdns. I've never had a problem delivering to gmail. For a while i had problems delivering to Hotmail/outlook, but participating in some sort of junk mail reporting program (JMRP i think it was) fixed that issue. Now, if i have deliverability problems, it's cause something broke, or my tls cert expired, or i added a new ip that the email server decided to start using. (Sorry for formatting, on mobile)
