“Spam: unsolicited email, usually of a commercial nature.”

Spam is the electronic version of junk mail, and has been around since the Internet was created. Spam filters are a way of filtering your email to remove unwanted mail based on a variety of criteria. You can block any sort of email, not just mail of a commercial nature. Blocked mail is deleted automatically – it does not even bounce back to the sender. These filters are quite flexible – some examples are provided after the instruction on how to add a spam filter below. All filters are cumulative.

To add a spam filter:

  1. Click on the Block an E-mail link in the Mail Menu area.
  2. Click on the Add Filter link.
  3. Click on the required header field in the first drop-down list. These are the various fields in any email message.
  4. Click on the required filter action in the second drop-down list. This action will act on the text entered in the third field.
    • equals – match the text exactly (whole words only). “Credit” will block “Credit”.
    • matches regex – matches the text based on regular expression (regex) rules. Regular expressions are a powerful but complex area. You do not need to use regular expression filters for most circumstances. Refer to these two good introductory tutorials – Using Regular Expressions and Learning to Use Regular Expressions – for more information.
    • contains – match the specified text in any circumstance. “porn” will block “porn” and “pornography”.
    • begins with – match the specified text when it is the beginning of a word. “porn” will block “porn” and “pornography” but not “teenporn”.
  5. Enter the filter text in the third field. This text is case sensitive.
  6. Click on the Activate button button.

Example:

To block all email from “john@paradise.net”, enter: From, equals, john@paradise.net

To block all email from paradise.net, enter: From, contains, paradise.net

To block all references to pornography, enter: Any Header, contains, porn
