Our experience with Postini was pretty good until Google bought them
out. When that happened some of postini's 'quirks' became more
apparent (black holed mails) and the service sorta went down hill from
there.
I'd recommend using a provider more *focused* on email that hasn't
been bought out by a giant advertising firm or getting an appliance /
rolling your own system.
I'd point out that Postini et. al. don't really save you that much in
terms of bandwidth. They aren't generally setup as store and forward
services, they operate by opening a backend proxy connection to your
mail server anyway, so you'll see header traffic, and most spam is
relatively small fry byte wise. If you're starving bandwidth wise,
traffic shaping and ratelimiting are better options.
Also, if you're an ISP, they won't solve the problem of outbound
scanning; that only applies to Enterprises.

Yeah, Postini is what we use today... been very good to date. Service
Provider pricing you can get them much more aggressive in pricing
depending
on volume. I believe we're doing about 35,000 mailboxes today with
them -
overall pretty happy.

I've had some really phenomenal experience using Postini. It's
pricing is
extremely reasonable at 12/year per user for just spam/virus
filtering. It
can do SMS/email alerts of host down and spooling until the server
comes
back up. The firm I work at uses it for about 1700 users and I have a
client I support of about 30 users that use it with extremely great
results.
Easy for users to use. Easy to implement for inbound and outbound
scanning.

They're consistently improving value to the service by adding

Hi Team,
I am interested in subscribing to a GOOD online email filtering
service,
through which all emails destined to an enterprise domain transit,
are
scanned and filtered for spam and viruses, before legitimate mails
relayed
to the destination mail server.
As a bonus, the service should also store emails for some time if the
destination mail server is down.
Much as IronPort and Barracuda appliances do a good antispam job,
they are
typically placed onsite for which reason the network bandwidth
still gets
chocked with arriving spam.
Please share your experienced recommendations with me on this one.
It's
better for me than following google search.
Felix
