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.

The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume.
