The Osirusoft RBL is/was flagging EVERY domain as a spam domain while
it was under a DoS attack. I am not sure if the service is still up
or not, but many anti-spam mailing lists and slashdot reported the
osirusoft problem and to stop using it immediately.
Spread the word to postmasters everywhere when you see bounces similar
to this one about the RBL doing what it is doing. Some people are
still not aware, and the result is bouncing every received message as
spam. If you yourself are configured to use relays.osirusoft.com for
anti-spam, change your configuration now.
Sendmail users....
If you have this in your sendmail.mc file, comment it out by prefixing
the line with dnl like this;
dnl FEATURE(dnsbl, `relays.osirusoft.com', `"Relay spam denied - see \
http://relays.osirusoft.com/cgi-bin/rbcheck.cgi?addr="$&{client_addr}')dnl
Then remake your sendmail.cf from it using an included Makefile or the
m4 command.
