[SOLVED] Zimbra 7 block email

[gromanenghi]

Good morning
I installed Zimbra
Release 7.0.1_GA_3105.UBUNTU10_64 UBUNTU10_64 NETWORK edition

I use Zimbra with mx records and how the outgoing mail server.
I set: smtpd_reject_unlisted_sender = yes
and smtpd_reject_unlisted_recipient = yes and I are denied the mails are not in my Zimbra server. My domain is gromanenghi.net

I want only from within my network can be sent as mail gromanenghi.net and I want to make sure that if I get an email from the outside that has the sender * @ gromanenghi.net is refused. E 'possible to implement this?

Sorry for my English.

Good Day
John

I have solved.
SPAM sourced from virtual domain user to same user

su - zimbra
# vi /opt/zimbra/conf/spoofprotection
gromanenghi REJECT spoofing....

#postmap spoofprotection
add into /opt/zimbra/conf/postfix_recipient_restrictions.cf
check_sender_access hash:/opt/zimbra/conf/spoofprotection

# postfix reload

and it's ok....
