It is, but whoever it was that said this greylisting implementation 
tends to 'just work' is about right, as long as you've followed the 
instructions and upgraded to a sufficiently recent version of Perl so 
you don't get memory leaks, of course.

So quite right, there is not much need for a lot of mailing list 
traffic. I'd be perfectly happy if this list was just used to suggest 
whitelist updates.

There are 'enough' people on this list for a degree of support to 
happen, and if you're really desperate, just wave cash at anyone (like 
me) who has a 'I am a linux consultant' in their footer, surely? ;-) 
Perhaps some kind of Wiki for this system would be in order though?

However I do wish people would learn to quote things at least a little 
bit and not include 5 footers in a row in their emails, or worse yet, 
the whole of the digest newsletter, and without even changing the 
subject of the message!

There's not *too much* (some, but not much) need to change MTA to get 
extra features, as stated...

My research on this ended up going for bm-milter (which does 
sender/recipient validation), which seems to work, and I've issued a 
number of patches (although I should update them) for it to better suit 
a virtual hosting environment with mixed onward destination types 
(mailboxes, virtual domains, mailertable), etc...

Of course you need to be careful about a number of factors, perhaps most 
importantly to have it run before greylisting; there's no point in 
greylisting for an address you already know does not exist, eh?

HOWEVER if anyone knows how to get the SMTP-timing based protections 
that Exim has (client must not send "MAIL From" before the "HELO" has 
been acknowledged, and similar for the "RCPT To" and "MAIL From") then I 
would be very grateful for a heads-up as it's really good functionality, 
apart perhaps from the log spam it generates. Sadly I don't think the 
milter framework is up to this?
