Interesting thread. Might I ask, what is the likely effect (if any) when one's Exim is configured to neither advertise nor accept 'pipelining'?

I've found that it stops a great deal of zombie-originated spam ever getting
past the connect phase.

Agree that as the general case - with a caveat [1].

- but what I am curious about here is if that (or some other setting) has the effect of forcing the above deliveries one-per-connect.

Which could/would change the (other) behavior under discussion. i.e insure they were flagged individually, not 'en bloc'.

-I think.... ;-)

[1] Pipelining not advertised: Aside from the 'free-range rude' we intend to ignore, our logs show that *sometimes* a legitimate hotmail delivery ignores us and tries to pipeline. Our guess is that one or more, but not all, of hotmail's many servers is configured differently from the others - which do not otherwise do this.
