Hi
I need to disable the Helo Restriction because when I send an email from Vcenter this appear as hostname.localdomain instead of hostname.nethserverdomain.
So How should I configure the “smtpd_helo_restrictions = check_client_access cidr:/etc/postfix/access.cidr, reject_invalid_helo_hostname, reject_non_fqdn_helo_hostname” parameters?
where is the main.cf?
Thank you for your help
Diego
