Hi,
Sorry if this is an old topic, but is Zen from spamhaus still working?
sure it is...
I used to see entries in my sendmail log along the lines of:
"550 Mail from "spammer-s machine listed here" refused - see
http://www.spamhaus.org/lookup.lasso";
And I don't see them anymore. Actually, I meant to ask this a few
weeks ago.
check your configuration. you would be too lucky if you don't get mail
attempts from zombies...
I haven't changed my sendmail config in a longtime.

time to add
