Just don't notify your users of viruses. I don't notify my users of either
viruses or high scoring spam. I quarantine for a short while high spam that
scores less than 30, and dump the rest. Low spam is the only thing that gets
passed and tagged.
If you let the users know that something was blocked, they are going to want
to see it because they always assume they know better. I don't even have
exec's complaining about it. Sure I have had a few FP's, but I get notified of
everything, and usually release the FP's before they know what happened.
Their time is too valuable to mess with the crap, and they pay me to watch
out for them.
MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
