You can block an e-mail using spam
filters. There are many definitions of spam, but one
particularly useful one is the following:
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. These filters are
quite flexible - some examples are provided after the
instruction on how to add a spam filter below. All filters
are cumulative.
