    Default HELO issue

    Hi everybody,
    we are experiencing some troubles with our outgoing mail: we are using
    Zimbra release 6.0.6_GA_2330.UBUNTU8_64 UBUNTU8_64 FOSS edition.

    SenderBase has decretated that out pubblic IP has a "poor reputation".
    Firstly it was by an incorrect FQDN hostname in HELO presentation.
    I fixed this doing (from Zimbra Forum):
    zmprov mcf zimbraMtaMyHostname mail.mydomain.com
    zmcontrol stop && zmcontrol start

    But at SenderBase they are very accurate: our IP is still "poor", now due to a non-literal HELO. To confirm this I get the following error if I try to send an e-mail to certain addresses:

    <info-at-domain-name.it>: host smtp-host-name.it[111.222.333.444] said: 554 5.7.1 <[my_pubblic_ip]>: Helo command rejected: IP literal in HELO hostname - please contact postmaster@domain-name.it (in reply to RCPT TO command)

    So I try to do this (from Zimbra Forum):
    postconf -e smtp_helo_name='my-helo-literal-name'
    zmlocalconfig -e postfix_smtp_helo_name='my-helo-literal-name'
    zmcontrol stop && zmcontrol start

    but nothing change... How can I resolve this issue?

    Thanks in advance.
    Fred
