Spam, Spamhaus, DNS Blackhole, cannot send email

Since an upgrade 3 weeks ago I’m receiving a large amount of spam.

Fresh CentOS 5 install and upgrade from 8 to Plesk 9 (with the most recent updates), now DNS blackhole lists, DNSBL is not working when I add spamhaus. If I add sbl.spamhaus.org I cannot send email using any email client (entourage, mac mail, outlook). Also when I add spamhaus and send a test email to [email protected] (spamhaus test email) their system returns an error message that sbl block is not working. I just added Barracuda’s new sbl block list and still using spamcop, no problem there. I tried switching to port 587 for outgoing email and it still does not work with spamhaus.

Has anyone had this problem? A fix?
