next time you show evidence, do not alter it. adding [] signs is useless
at best.

- use reject_non_fqdn_helo_hostname
- if you have a recent postfix, use
    check_reverse_client_hostname_access hash:/etc/postfix/host_acl
    check_helo_access hash:/etc/postfix/host_acl

== host_acl
.user.veloxzone.com.br REJECT

- use a content filter (spamassassin....)
