You can block an e-mail using spam filters. There are many definitions of spam, but one particularly useful one is the following:<\/p>\n Spam is the electronic version of junk mail, and has been around since the Internet was created. E-mail filters are a way of filtering your e-mail to remove unwanted mail based on a variety of criteria. You can block any sort of e-mail, not just mail of a commercial nature. Blocked mail can be deleted automatically or sent to another e-mail address or script.

All filters are cumulative.<\/p>\n Useful anti spam links:<\/p>\n http:\/\/www.spamrecycle.com\/antispamthings.htm<\/a><\/p>\n http:\/\/spam.abuse.net\/overview\/whatisspam.shtml<\/a><\/p>\n http:\/\/www.cybernothing.org\/faqs\/net-abuse-faq.html#2.1<\/a><\/p>\n Also refer to Spam Assassin for another approach to dealing with spam.<\/p>\n To add an e-mail filter:<\/p>\n Click on the E-mail Filtering link in the Mail area.<\/p>\n Click on the Add Filter link.<\/p>\n Click on the required header field in the first drop-down list.
