chand311 The best anti-spam measure is to be a bit savvy about the way you use your email account!
Try to avoid opening spam emails and clicking on links in spam messages.
Don’t buy anything from a spammer. Not only do you risk comprising your security and infecting your computer with malware - viruses and so on - you also reward and encourage the spammers.
Don’t be tempted to reply. The mailbox is probably unread.
Don’t threaten the spammer. Some mails will be seen and spammers have rights too. Threatening messages could expose you to legal action.
Avoid ‘unsubscribe’ options. Cynically, spammers often include an ‘unsubscribe’ link. Far from removing the menace, clicking it will confirm that your address is active and probably attract even more spam.
Use a disposable email address. You could use this account especially for buying online or writing to newsgroups. If you find that you are getting a lot of spam at this address, you can simply delete it and set up another.
Be wary about giving out your main email address. If in doubt, it is a good idea to use a disposable address (see above).
Never reveal your email address on your website. If you have a website, putting your email address on it will be easy fodder for a ‘spambot’ that is harvesting addresses. You could use a web contact form instead.
Munging. A simple but effective technique where you present your address in a way that people can easily work out but which will fool spambots. They will look for a pattern, such as <email removed>. Writing the address as ‘a at b dot com’ would probably evade them.
