There are three ways you can deploy an anti spam filter solution:
On site spam filters - Spam filters are normally installed on
your mail server, or on a separate machine inside your office. This adds to
your internal administration costs, by adding another system you must maintain,
patch, and backup. The IT Administrator has control over the entire system, but
also has to take responsibility for it. Users call IT staff when they have
a problem with spam and request that it be handled.
Client side filters - Spam filters can also be installed on
individual machines for filtering each users email. This gives the individual
user the best control, but adds greatly to the cost (a license per machine),
and requires even more maintenance for IT staff. It can also add to tech
support costs internally as users mis-configure their own spam filter and
request IT time to fix it. This solution is generally acceptable for home
users, but not recommended for companies of more than a few people.
Managed spam filter service (sometimes called a third party spam filter or
MX spam filter ) - The spam filter is offsite and managed by a
third party. The service should be robust, and have adequate resources to
support your needs. Ideally the spam filter service should protect your systems
from spammers, and provide backup capability in the event your server is
offline. Administrators should also have full control over the settings for the
entire domain. Ideally tagged spam should not require an Administrator to
retrieve the email for a user. This can quickly become a resource drain as
users want to check the quarantine to see if they missed any email.
