hi.

I have currently configure a postfix server using the tutorial from
http:/jimsun.linuxnet.com/misc/postfix-anti-UCE.txt . I use exactly
the same configuration there but somehow all outlook email sending out
from my LAN got block by the postfix server. I have to move the
"reject_invalid_hostname", and " reject_non_fqdn_hostname" after
permit_mynetworks for email to pass through postfix.

What i don't understand is , isn't smptd_recipients_restrictions
meant for the "recipient" restriction rather then sender ?

smtpd_helo_required = yes
