[vPostMaster] weird load issue

[Wallace Winfrey]

Just wanted to give a follow-up on this issue, we switched from 
SA/ClamAV to Postini almost two months ago, and not only has the spam 
volume been decreased (by at least an order of magnitude), but not 
having to run SA and ClamAV on every piece of incoming mail (we still 
use it for a few things) has led to an incredibly dramatic decrease in 
our mail server's load average. I've attached a Munin graph to illustrate.

If you find yourself having load issues, I would definitely recommend 
checking into Postini. Google recently began offering Postini filtering 
at a reduced price (basically, it's cheap, but your support options are 
limited to community forums and pay-per-call phone support). We're 
getting Postini filtering through our ISP, but if that option wasn't 
available to us, we'd likely have gone with one of these plans:

For what it's worth, we have had to use the phone support once since 
migration.

cheers
