2. Audience
The intended audience is mail system administrators, who are
already familiar with such acronyms as SMTP, MTA/MDA/MUA,
DNS/rDNS, and MX records. If you are an end user who is
looking for a spam filtering solution for your mail reader
(such as Evolution, Thunderbird, Mail.app or Outlook Express),
this document is not for you; but you may
wish to point the mail system administrator for your domain
(company, school, ISP...) to its existence.
