Well basically procmail is a Local Delivery Agent , which means that 
once configured correctly
it can deliver  mail to various folders per user command . Now if within 
a procmail recipe someone
calls for example spamc ( spamassassin ) then it can filter spam 
messages also .

Am not sure that i fully understand that . Fetchmail fetches email from 
the remote POP3 Server
then it alters the To address as to make it suitable for local delivery 
. Then it passes the email to
sendmail . Now sendmail tricked by the altered To address believes that 
the email is for local
delivery and for that reason it passes the email to the local mailer as 
defined in sendmail.cf /
sendmail.mc , which in Fedora installations is procmail .
