(Snip good suggestions about reducing the number of mails hitting Amavis.)

So, I've *massively* reduced the number of mails going to Amavis simply by
reducing the number of mails being allowed to go through the MTA. It looks
like roughly 1 mail per second going through Amavis, which correlates with
the number of received mails per minute (mpm) on mailgraph [1].

We can handle 75mpm, *internally*, no sweat. Realistically we can handle a
heck of a lot more, even before we give Amavis more head room (cranking up
its max_servers/max_requests, etc).

So, certainly something to think about in the future, but now that we have
good information about the behaviour of our mail load, we need to watch it
for a while, to get a better grip on it over a useful period of time. Then
we can start thinking about further optimisations.
