      Hi guys,

      My postfix has been configured to not accept mail from anyone@...
      if it was not
      generated inside my network and it has been working gladly.

      But I've got some massages that apear to pass through this configuration,
      whose example
      follows below: See the lines enclosed by [ ]. The first one shows that it's
      an IP outside my
      network and the second one forges an address of my domain "Ana
      Carla"@....

      Does anyone know how can I block this?

      Thanks.

        ... 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

          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....)
