You need to get a proper self owned ip range with your own WHOIS info for your mail server.

On google I found that one can get a IPv4 /30 subnet for about 11 USD a year.

Not a huge amount of hosting companies support Bring Your Own IP do they?

More do than you'd think.

But for IPv4, true BYOIP isn't really possible for less than a /24 block, which is overkill for just selfhosting personal email.

It also usually involves needing to set up a company to own/lease the block if you haven't already got one.

By definition most of them won't because it's a complicated mess.

Can you link to this please? Everything I see seems much more expensive...
