I use OVH. Unlike AWS/EC2, OVH gives you virtual
console access, so any problems with booting the VPS
can be investigated and solved. Their only restriction
(if I remember correctly) is that you must not do any
port scans or anything illegal from their VPSs.

Advice: If your IPv6 address ever gets added to an RBL
because the RBL refuses to accept that IPv6 addresses
can be assigned individually, and someone nearby is sending
spam, you set can set "smtp_address_preference = ipv4"
in Postfix's main.cf to only use the IPv4 address to send
email (while still allowing the IPv6 address to be used
to accept mail). I had to do that because another OVH
customer is presuably sending spam.

By the way, a good tutorial for setting up postfix
and all the addons can be found here:

  https://www.linuxbabe.com/mail-server/build-email-server-from-scratch-debian-postfix-smtp

There are 12+ parts to it. I used it for setting up
SPF/DKIM/DMARC. The rest is probably good too.
