Avoid double scanning from MailScanner

Hi All,

MailScanner -> then to the filter script -> then to UUCP -> then to
alternate postfix server.

The Mailscanner is invoked with header_checks through
header_checks = regexp:/etc/postfix/header_checks

cat /etc/postfix/header_checks
/^Received:/ HOLD

The filter is invoked with smtpd options from m

Block forged addresses

Hi all,

I was wondering what choices are there to block forged sender email

Many thanx
