Blocking email
You can block an email using spam filters. There are many definitions of spam, but one of the most useful ones is the following:
“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:
-
Click on the Block an E-mail link in the Mail Menu area.
-
Click on the Add Filter link.
-
Click on the required header field in the first drop-down list. These are the various fields in any email message.
-
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”.
-
-
Enter the filter text in the third field. This text is case sensitive.
-
Click on the
button.
