If it sends a message a day, it cannot be spam (by the B in UBE).
This isn't true. Are you really unfamiliar with the "snowshoe" tactic
used by spammers? It has been common for well over a decade. Originally,
showshoers would get disjointed /24 blocks from one provider, then they
graduated to /27s spread across multiple providers, now they stand up a
few VMs in multiple zones of multiple self-serve 'cloud' providers. They
spread the distribution work across many source IPs so that none seems
to be sending "bulk" mail.
"Bulk" isn't about the delivery path, it is about how mail is composed
and targeted.
I've argued before that we should have better handling for the
smallest
servers (whitelist the first 5 messages/day for low volume IPs, for
example),
Yes, please :-)
There don't seem to be big advantages for Google in killing small
servers.
Google is a mostly automated advertising company supported a massive IT
operation. Every small server represents eyeballs they can't readily
capture.
