Please turn off HTML.

 $ telnet localhost 25
 $ ehlo localhost
 $ mail from: root at localhost
 $ rcpt to: someuser at localhost
 $ data
 $ Subject: Mail using Postfix
 $ Hello there.
 .
 quit

Logged in as someuser do
 $ mail

For saildirs, add
 home_mailbox = Maildir/
to /etc/postfix/main.cf
 $ /etc/init.d/postfix restart
Test with TBird etc.
