I went down the clamav.net page and emailed some of the companies there.
One response I got from Linux Network Care seemed very reasonable for
small domains that run Microsoft Small Business Server.
- 40$/hour and one hour minimum for each domain
- 5$/ per domain and 5000 emails per month
Not sure what happens after 5000 emails, but I'm gessing that it would
just forward directly to my MTA. I'm assuming that my MX records would
be something like:
--MX record 0 pointed at the managed ISP
--MX record 0+ on my email servers
And if the managed box went down, mine would then automatically handle
the email, right? Also, I'm assuming that a such a service would not
affect my working http://mail.domain.com/exchange OWA (Outlook Web
Access) setup.
I have a nonprofit that I help out (Family Services in Moreno Valley,
off Box St.). I think that I'll set something like this up with them, as
they often don't check to make sure that the AV updates are working
properly.
