Hi,

I have a Postfix server setup as email gateway to filter out spam and
virus emails before they reach our exchange server. Before actually
accepting a email I have some checks setup:

smtpd_recipient_restrictions =
permit_mynetworks,reject_unauth_destination,reject_unlisted_recipient

smtpd_helo_restrictions =
permit_mynetworks,reject_non_fqdn_hostname,reject_invalid_hostname,reject_unknow n_hostname

Some system admins do not have there email server setup properly and
there requests get a 450 or 550. Because of this I would like to
whitelist certain ip's. How would I configure Postfix to accept email
from these broken email servers I choose to whitelist?

Thanks in advance for any relpies on this.
