We use zimbra OSS on SLES10 SP1. Zimbra has spamassassin built-in. At
the present time, my mailbox is filled with backscatter; getting
around 10 a minute since 4:30 today. I have postfix backscatter rules
in postfix of zimbra, http://www.postfix.org/BACKSCATTER_README.html#real
but still getting pounded. Here is the header from on such mail:

Can someone please help me stop this? A while back, there was a thread
that pointed to a website, backscatter.org or something like that,
that we used that since the upgrade did a wonderful job. Anyone
remember that web site?
