Setting up a VPS as a mail relay, with the mail storage locally

Hi,

I have a basic VPS that I have configured to mainly act as a wireguard
server. Recently I set it up as a mail server using the ISPmail
tutorial and it works fine.

I'm looking to expand my mail server and would rather primarily use my
local machine for better performance (for stuff like clamav and more
storage) and setup the VPS as a relay instead so that all mail related
will come in and out of the VPS still rather than my home network. I
would try and go for routing the ports using wireguard, but [this comm
ent](https://www.reddit.com/r/homelab/comments/a81zxg/comment/ec7r7fa/
?utm_source=share&utm_medium=web2x&context=3) suggests mail could
still be received if my home machine is down.

I've done a bit of looking online, but am struggling to find a
tutorial or similar that would help me pull it off well.

If anyone has anything to help or other options to help me achieve
something similar please let me know.

Thanks

Aren't the IPs associated with VPS providers borderline banned by
major mail providers meaning everything immediately gets marked as
spam?

It is on a list unfortunately. I do want to try and make it work
myself and if I decide to use it more I'd probably move to a proper
relay service
