I run my own e-mail server too and constantly run into issues:

If I send a new person an e-mail, I have to contact them on Facebook and tell them to check their spam folder. Fuck Google and Microsoft and their terrible e-mail filtering. Just because people are so dumb they will open any ransomware sent to them doesn't mean you drop all e-mail you don't trust with no way to account for it.

How long have you been sending mail from your latest IP Address?

I run some websites that have their own mail servers. One thing you didn't mention which can help is to be sure to use an email signature. Basically short emails are more likely to be flagged as spam, especially if there's an attachment.

In use 12 years, only ever used to reply (except when messaging businesses), never done mailings. Of course there is a footer with bricks & mortar address, phone, unsubscribe link.

Had problems with hotmail before, it's just associated IPs being factored in too strongly. Same ISP has an IP address that spam has been sent from; support responds with won't fix. In their favour at least they responded.

Domain has SPF but not DKIM.

Thankfully no other mailbox provider blocks us. We could pay to be added to the third-party "friendly" domains list of course ...

I'm surprised they wouldn't whitelist our domain but leave it on a tight leash.

Why don't you properly configure DKIM and SPF? Then you won't have this problem.

From the fine article he linked: SPF, DKIM and DMARC are all domain verification systems for validating e-mail’s origin to prevent spam. I have all three records set in DNS records for all the domains I send e-mail from, verified they were correct using testing tools, and I still get flagged as spam.

Google uses a lot of signals. The article above is on http, I saw a drop in spam flagging when the web host on my email domain was https only.
