Configuring Anti-Spam

Introduction to Anti Spam

With fraudulent, inappropriate and offensive emails being delivered in vast quantities to adults, children and businesses every day, spam protection is an essential component of your network's security strategy. Spam wastes network users' time and network resources, and can be dangerous too. GFI MailEssentials tackles spam protection at server level and eliminates the need to install and update anti-spam software on each desktop. GFI MailEssentials uses methods to identify spam:

Use of Blacklists & White lists - this method uses blacklists to block mails from known spammers. White lists are lists of email addresses from which you always wish to receive mail.
Bayesian analysis - this method analyses the content of the inbound mail and based on mathematical rules decides if the mail is spam or not.
Header checking - this method analyses the header of the mail to detect whether a mail is spam or not
Keyword checking - this method allows you to configure keywords which indicate if a mail is spam.



Anti spam configuration

When GFI MailEssentials finds a spam message, it can delete the message, move it to a central folder, forward it to an e-mail address or move it to a users junk mail folder.

Note: To stop spammers from relaying their mail through your mail server, you need configure your mail server to disallow mail relaying. For more information on this, consult the mail server documentation.
