How do i check valid sender before sending mail?
FROM: anonymous at mydomain.com
if this 'anonymous' user is not on localhost the mail should be rejected even if the user has valid login (user and password).
my sendmail uses login/plain before relaying. however they can still send mail even the FROM: header is not their name. I don't want this to happen.
Need your help guys.
