How is your email deliverability though? My main issue was having my mail sent to spam even if my IP was clean. I resigned and moved to O365 and haven’t had issues. But I hate that I had to do that.
Not OP, but I have had deliverability problems with only one provider, and that is outlook.com. They seem to not care at all whether you have set up everything correctly (I pass all checks for reverse DNS, SPF, DKIM, etc., and I am not on any blacklists) but just have their own shitty whitelist of senders and throw everything else in spam. I had to throw in the towel and send through an SMTP proxy hosted by my VPS provider which solved all issues.
Please try to avoid using O365 as they literally are the main culprits that make self-hosting email a pain in the butt.
I've set up everything according to best practices (SPF, DKIM, TLS, static IP for almost a year, reverse DNS, blacklist removal, spam checks).
I've also repeatedly contacted Microsoft support to get unblocked. All my requests to whitelist the IP in the last year or so have been ignored.
Microsoft is the sole bad actor I've encountered in more of a decade of self hosting email.
On principle, I've decided not to use a different provider, and users on Microsoft services will not get emails from me or from my websites.
This will only change if enough people complain. As a paying O365 customer, I'd encourage you to open support tickets that you're not receiving emails from some the smaller email servers, e.g. those hosted on DigitalOcean.
same experience.. I run a small ISP. we only take paid clients so no one is a spammer (other than lost passwords). no delivery issues elsewhere. yet Microsoft filter absolutely everything into spam.... emails to support just get a "your request has been denied as not applicable" or some such junk
No problem at all. I do not host from home because the IP's of private cable providers are blacklisted in spam lists, but from a colocation in a small data center.
Not the OP but I have a similar environment, and do not know of any deliverability problems. Early on I found mails to one or two providers, like Yahoo and some Canadian ISP were bouncing, but I got a new IP and those troubles went away.
