Tips to reduce spam
Talk to your e-mail service provider. The majority of spam is easy to detect and should be rejected before it gets to your account. Some e-mail servers are better at this than others.
Don't submit your e-mail address on the web. Web pages that ask for your e-mail address, particularly when offering something for “free”, are the most common way of harvesting addresses in order to spam them. If you do need to use your address for this purpose, open a free e-mail account from a provider like Hotmail or Gmail, and use this address on web forms rather than your main one.
Use a spam filtering e-mail client. Most modern e-mail clients include a learning spam filter that will automatically detect spam and remove it from your inbox. These do take a little bit of training, you need to mark messages as spam or not spam initially. If your e-mail client does not include a spam filter, we recommend Thunderbird from www.mozilla.com .
Mobile Computing have developed spam fighting e-mail servers which block almost all spam before delivery. Domain e-mail hosting is available for up to 100 e-mail accounts for $120 per year.
