Spam are unwanted emails, usually adverts from affiliate type companies.

1. Avoidance: Don't leave your email address on any website, as programs harvest these automatically. Don't signup for anything, unless from a reputable company. Possibly use a hotmail address for this sort of membership.

2. Removal:

a. Your ISP can often remove most of it for a small monthly fee, but ask how you can access these emails in case good email is removed.

b. Software on your server can remove spam, there are products that hook into Exchange eg Trend's scanmail. 5 users will cost about £150-200, & then £50-£100 pa.

c. On your client PC, install a spam removal program, for Outlook users, I recommend Cloudmark.
