Scan Messages = %rules-dir%/scan.messages.rules

1) nope, email addresses are not case sensitive.
2) Envelope, MS always uses the Envelope-from in from parsing.
3) this is the 'big knob' that tells whether MailScanner scans the email or
not. Way before it's passed to SA, anti-virus or checked by mailScanner
again RBLS (independently of SA). etc. Be very careful with setting as it's
basically sending email through with zero scanning. Might want to look at
the the "Is definitely Not spam" setting. Normally this is only used for
trusted ip-addresses not email 'from' addresses.

hope that helps
