[SAtalk] new user of spamassassin

[Ceva]

Hi everibody, I a new user of spamassassin, so I have some doubts. I installed spamassassin at a server running FreeBSD 4.9 and sendmail. I want to know how spamassassin works. Exmaple: Should I tell something at local.cf to spamassassin to work with sendmail? Someone can send me a local.cf example file? I am still not using razor yet, this is for future.   Thanks in advance   ceva
