We've deployed this for a few clients specifically as a proxy. Not
extremely large systems, mind you -- around 100 users at one site and 300
at another, a couple thousand e-mail messages a day at each site, I'd say.
(One every two to three seconds getting processed through).

I've done it on both RedHat 6.2 based boxes (glibc 2.1) and RedHat 7.x
based boxes (glibc 2.2).. both work just fine. Using 2.4 kernel in both
cases, and MD 2.9-2.15 with SA 1.20.
