[Mimedefang] Tracking down the delay (Razor timeout!)

Thanks, this seems like good advice!  I already had rbl_timeout at 5 so 
I shortened razor_timeout to 5 also and sure enough, my delays are ~10 
seconds now.

I may have narrowed the problem down to razor.  Looks like I'm getting 
intermittent delays (which could explain why I have sometimes run 
spamassassin all the way through without delay.)  Often I run this once 
and it completes quickly, but the 2nd and all subsequent attempts razor 
hangs on timeout with wonder.cloudmark.com:

# razor-check -d -debuglevel=9 /tmp/spam2.txt

(Pauses here for long time)

So I guess my questions now are:  How do I find & set up a good, 
reliable set of RBLs?  Do I need to invest a lot of time or can I 
automate it?  Is this an anomaly with cloudmark's db/service or does 
this kind of thing happen a lot?  (PS: I re-initialized my razor client 
but it hasn't helped.)

My apologies for dumping my razor problems on the MD list... If it 
weren't for great software like MD, I might never have bothered with 
spamassassin, razor, etc...
