Hmm,
I might be wrong on this, but don't their terms of use exclude any use
of the service for anything other than amateur hobby usage?

They are only for personal and non-commercial use, says section 3 of
those terms..

Good morning
Cloudmark's Spamnet does something like that. When installed on a
machine it collects data on the incoming mail from all the thousands of
clients that are running spamnet and continiously updates a database. It
also is now supporting sender id according to their website.
www.cloudmark.com
I running it here and of the 5 different systems we have used, it has
been by far the most effective.
We are not associated in any way with Cloudmark, just a very happy user.

Subject: [spf-discuss] Co-operative 'bulk mail' alerting
It occurs to me that receivers with large numbers of
subscribers (AOL, MSN etc.), by caching and monitoring the
source IP address of received messages for a few minutes, can
alert themselves to probable sources of spam, viruses, etc. I
think I've seen AOL say that they do this as part of their
battery of anti-spam activities.
Those of us with smaller domains cannot gain the same
advantage from such an alerting process - it needs 'scale'.
It occurs to me to form a 'club' of small-scale MTA
operators. We find a way of collating current observed
activity, so that we can jointly be warned that a host is
spewing out large volumes of mail.
I don't plan any judgements about the messages, no spam vs.
ham decisions, no long-term history.
Just something very simple with, say, a 1 hour time horizon.
There may be some advantage in including in the alert details
of any SPF test results relating to the source.
This is much simpler and light-weight than GOSSiP.
I'm not asking at this time for comments on feasibility,
desirability, etc.
My one question is: Does anyone know of anything like this
that's already out there?
Thanks
Chris Haynes
