Without those changes in place (more exctly, using the Debian/Linux
defaults) a Dual PII-333 on the end of a Tier 2 T3 has regularly
sustained just under 1,400 deliveries (to target MX) per minute for
me.  While I've not maintained that level for more than single digit
minutes (not enough traffic) that sums to 80K messages per hour.
I've been happy enough with those numbers for the box in question
that I haven't looked further.

And no, it doesn't even begin to saturate available b/w.

I do have this set.  I also have a local copy of BIND 9 listening on
localhost only.

FWVLIW I typically have between 1,500 and 2K messages in my queue on
that machine (my hobby box), all for slow/down MXes.
