What if I keep getting e-mails from the same person or company and I don't want them anymore?   Just add them to the Spammers Analyzer.  This analyzer overrides all analyzers except for the Friends Analyzer.  Just add the e-mail address of the person or company and they go straight to the Mail Jail.  Use wildcards to eliminate all e-mail from a company.
List all the e-mail address of known spammers.  If you don't want to see another e-mail from someone, just add their address to this list.  Use the '*' to remove an entire range of e-mail addresses.  Put in '*@BADCOMPANY.COM' to block all e-mail addresses with @BADCOMPANY.COM in them.  E-mails are not case-sensitive, so don't worry if the letters are all capitalized.
Spammers supports limited wildcards.  You can put a * at the beginning or end of a word.  Example: *@BLASTMAIL.COM would block all e-mail addresses that end in @BLASTMAIL.COM.
To block e-mails that use various subdomains, like out@mailout.blastmail.com, or out@outgoing.blastmail.com, etc., then you can add *BLASTMAIL.COM to the Spammers list to catch all of them.
