Well, I haven't followed this thread much at all, but if you haven't already, you
may want to separate your clients onto two distinct servers: one whitelist, and one dirty
list. This will have the effect of easing your worry, and may allow you to isolate the
reason for the disruption. If that reason is not to your standard user agreement, you
might be able to persuade your dirty list users to curtail their questionable practices.

I will have a look at greylisting, but I recall from
when lug.org.uk
implemented it that there was significant impact and delay with emails
coming through and again this will lead to issues with clients calling
me about emails that they were expecting.
Email is not a real-time service :)
With this implementation, the only one from any address that is delayed
for a few minutes is the first one. After that, they're in the accept
list and go straight through.
An interesting thing I have just found from analysing
todays logs is
that almost all are being sent to email addresses (mostly rubbish names,
e.g. message IDs) at a single client's domain name. Is there a quick
way in Exim to apply additional rules just to one domain (such as
greylisting or strict application of RBLs)?
How large is the number of legit email addresses?
