In article <CAArzuot9dGV8N0PBY4P2=u=N_a2T36Y1kR6W4VeeYR+jYgS4LQ () mail gmail com> you write:
Did your customer set up an MX for their domain pointing to postini
and then forward it to you?

obsmtp.com is Postini's outbound servers for customer mail.

In my experience, they gush spam, and Postini management has been
impressively hostile to the suggestion that a spam filtering company
should, you know, filter spam.  On my smallish mail server, I direct
nearly all of their mail into the spamtrap, picking out only a handful
of envelope domains that I've observed sending legit mail.

I run a smaller email filter service for clients and starting Saturday, we
are experiencing heavy traffic aimed at one email account.  99% of the
traffic is coming from obsmtp.com servers.

In the last 24 hrs, we have been getting over 1,000 attempts per hour to
this account with a couple of peaks at 4,000 per hour.

Not sure if they can help but an offlist contact from them would be nice.
