Hi all, just want to get an idea of what everyone things is best for
small business anti-spam? We have our own mail server, but should we
look at a plugin to the server, our own anti-spam server
(linux/spamassassin?), client/PC based anti-spam software or maybe even
a service like messagelabs?

I would love to hear what small business users are doing at the moment,
what works and doesn't, both from features and costs.
