John,
What my users expect is the level of speed and reliability of email that
they have always had over the years with our ISP, up until 2 months ago
when I took over with our new server. It was fast, reliable, mostly
spam-free, and free of false positives (that they ever noticed, anyway).
I can't go in and try to convince them that in the last 2 months that
I've been in charge of the mail server that the world's email has become
slow, unreliable, and spammy.
I've got to come up with a solution that is as good as what our ISP
provided.
The good news is that by conservatively (OK, maybe not always so
conservatively. I was a little desperate at first) adding strategies in
Postfix and SA, I guess I'm nearly at parity with our old ISP. Allowing
for a bit of sugar-coating of their descriptions of the good old days,
maybe I'm even already there.
Until we do our server OS upgrade, I don't have postscreen. But the 1
second sleep after smtpd connection seems to have been the finishing
touch on our spam control. It seems about as effective as postgrey.
Personally, I detest those web mail forms. I, too. expect to be able to
compose an email, send it, and have it received within a minute. And I
do not think that to be an unreasonable expectation at all, as long as
we administrators keep our feet on the ground and don't start doing
stupid stuff like greylisting.
Though, as been pointed out by Daniel, greylisting may be appropriate in
certain contexts.
