Yea, the big corporates do not want anyone to run their own email servers now, and I may end up giving up, as no longer really need a VPS as I am retired.   Email servers that are not a run through big corporation  are by definition suspicious.

At one time I ran Tor with a separated IP address on the server in and out,  but blacklisting sites soon worked that one out.    I have VPS for Tor are elsewhere not on my personal VPS.    

Email servers are tedious to set up SPF, dkim ,dmarc, certificates and fail2ban.  Even with that all in place, and on no blacklist whatsoever (as listed on MXtoolbox) both Google's email systems and Microsoft can suddenly, you to their email accounts.   They never give a reason.   I had this twice now. It is a real chore finding their hidden web pages and forms to deal with the issue to get you off their internal backlists, and it takes a few days.   Because my email server has so little traffic, is it impossible to earn "reputational" good marks with them. So one glitch probably triggers their algorithm to block.

Looking at your email address, you have an ISP assigned email. Unless you work for Spectrum, you shouldn't use an ISP email account. I'd advise you either:

  * Sign up for a third-party email service like Gmail, Outlook, ProtonMail, or Tutanota

  * If you can maintain one, run your own email server (I do this myself but many don't recommend it as email servers are complex)

Assuming you have a middle relay, I don't think the relay caused the email problems. I believe someone hacked your email, whether through a hacker attacking the Spectrum email server or a virus/malware gaining access to your email via a browser exploit. Check for this first.
