This screen allows you to add to your black list. Note that regular expressions
can be used so you can modify the Email address below to be any
portion thereof or specify a regular expression. Here are some examples.
Given an email address of Spammer@spamdomain.com you can:
Specify just the domain (e.g. @spamdomain.com). This will effectively
black list everybody from that domain.
Specify just the username portion (e.g. Spammer@). This will effectively
black list anybody using the username of spammer (note that email addresses
are not case sensitive) from any domain.
Use regular expression characters to further refine your filter.
For example, "^spammer.*@" means any email address that starts (^) with
the word "spammer", has any number of characters after (.*), then an "@"
sign will be black listed.
Warning
Care should be taken when using regular
expressions as you can easily black list email messages you do not want
to have blacklisted!
