Likewise, I prefer the Win32 Native mode as well. Our Mail Server performs
exceptionally well with CLAMAV. We don't use SpamAssassin as we have an
all-in-one mail server that works for our needs. Surgemail by Netwinsite is
the least expensive, Full featured mail server we found out there and
feature request/bug updates that have a minimum of 8 business hours to a max
of 40 business hours turnaround is something I prefer to have and is NOT
available by any other mail server vendor I have seen to date.
My old Mail server vendor, Rockliffe Mailsite, took forever to release new
features and updates to fix bugs, let alone that I had to develop the mail
sieve filters for the community to help reduce junk mail for all as in
interim... until I got fed up with the 100% nailed up CPU for about 100k
daily messages. Plus it costed almost 10 times more than what Surgemail
costs. Surgemail is Multi-platformed too.
ClamAV in daemon mode works beautifully with this product (even though it
also has its own AVAST AV plugin, they support third party AVs.) My CPU on
the mail server, which processes about 250,000 messages daily, never exceeds
7% and averages around 5% with both mail server and ClamAV running. CPU is
only a Athlon 1700+ with 1gb ram. Currently for the past 24 hours, CPU
average is about 2%.
If you guys really want to lock things down, consider turning on SPF and DK
authentication only. Watch the Spam level drop 95+%. Only issue you will
have are other domains who refuse to add either a SPF or DK signature. With
modern times, calls for modern security measures. Upgrade or be left behind
is what I think most mail admins should be doing. We warned incoming
clients, 1 year beforehand, who did not have a minimum of a SPF record and
let them know that their domain will no longer talk with our mail server if
they did not have one. Virus activity went from an average of 45
messages/hour to only 3 messages/hour.
Therefore, if you really need to protect your clients, It is not only that
you need to put in an Anti-virus solution to work, you also need to start
securing your mail server with modern recommendations to reduce the spread
of the viruses as well.
The one thing I would really like to see is if ClamAV can run in service
mode natively. Then I would not need to login the machine after a restart
to start up the dos batch file to keep it up and running.
