Some back of the hand numbers, since this morning I switch from Redhat  
7/IMP 3.1/Horde 2.1 to Fedora Core 2/IMP 4.0.1/Horde 3.0.2.  In short,  
I don't think this is going to work.

Old machine uses stunnel, new uses imapproxy/PHPA.  Old machine ran  
with a laod avg of 1-2 in the middle of the semester. New machine is  
now at 25-ish, and not looking like it's going to make the day. It's  
looking like we'll revert to IMP 3. It's crashed twice, once due to  
100-s of thousands of liens of this in the ssl error log:

Once we firewalled that guy things got a bit better, i.e. LAV 25-ish.   
We're still looking to see why Apache is running full tilt....
