Cheap US$5 cloud instances are super attractive propositions for spammers who
have absolutely abused these providers and made it difficult for legitimate
senders to host on them.

I have DNS, SPF, DKIM and DMARC under control. But, IP/ASN reputation is
something that I have to factor in because a lot of my counter party receivers
are on Office365 and G Suite who would block ill reputed networks.

True, I remember seeing some statistics about spam originating from them and
that is why they have recently started blocking ports 25 throughout.

Does your AWS instance receive and send over port 25?
