Mailscanner not scanning e-mails

[SW]

I've installed Mailscanner 4.25-14 on a Raq3 server but I think I did
something wrong because e-mails are not being scanned by mailscanner (no
e-mail headers are being added X-MailScanner). I've checked to make sure
mailscanner is running and everything seems fine:

[root at ns1 admin]# ps auxw | grep -i mail

I think my problem occured when I tried to follow the instructions I
followed (    ) about moving the mqueue/q*/* etc. Can someone help on what I
should have in sendmail.conf and Mailscanner.conf to scan e-mails.

BTW, I also installed f-prot and spamassassin on this machine to work with
mailscanner.

Thanks,
