Can anyone help me?

[David Zinder]

I think my problem is related to surbl.org, but I can't figure out how 
to reach them. list.surbl.org times out, and has for several weeks.

I had been using Spamassassin 3.1.5 under RHEL 3. Works great, until Jan 
1, 2008. I started getting false positives from surbl. These are emails 
I have received for years, such as newsletter.varbusiness.com and 
newsletter.crn.com. If I remove file /usr/share/spamassassin/25_uribl.cf 
and restart spamd, the false positives stop, but more real spam gets 
through. I upgraded all the perl utilities SA needs and I am now running 
SA 3.2.4, but the problem is still there. I can't find anything on the 
SA or surbl web sites that address this problem. Anyone have any ideas?

Thanks in advance,
David
