As an anecdotal aside, approx. 70% of incoming portscanners/rdp bots/ssh bots/etc that hit the firewalls at my sites are coming from AWS.
I used to send abuse emails but eventually gave up after receiving nothing beyond "well, aws ip's are dynamic/shared so we can't help you"
I tried, once upon a time, to run my private SMTP server as an AWS machine. What a disaster, even with a rubber band IP or whatever it is they call a static IP assignment. Tried sending through SES and that was just as bad. Moved it to a Linode and set up the appropriate DNS including the rDNS delegations and it has been perfectly fine (both on IPv4 and IPv6). I do recall having to do something to get it to initially work (maybe Linode does some outbound blocking of port 25 -- I don't remember exactly as it was several years ago). I know of a couple of other folks that run SMTP on Linodes and a couple of big mailing lists as well, all of which seem to work with no problems. Never had any problems with any listings on any of several hundred DNSbl either. Plus of course it is a pretty cheap way to get a reliable server (albeit virtual) on decently connected and configured infrastructure.

Amazon's cloud operations are a constant source of spam and abuse (e.g., brute-force SSH attacks), they refuse to accept complaints per RFC 2142, and -- apparently -- they simply don't care to do anything about it. I've had SES blacklisted in my MTA for years (among other preventative measures) and highly recommend to others. ---rsk
