    Default Didnt get the 0-day announcement/warning because Zimbra mailservers dont reverse DNS

    basic spam filtering includes rejecting mail from servers without reverse DNS. Zimbra is a mail server company. Should know better.

    Dec 30 03:16:19 foo postfix/smtpd[5530]: NOQUEUE: reject: RCPT from unknown[162.209.122.178]: 450 4.7.1 Client host rejected: cannot find your reverse hostname, [162.209.122.178]; from=
    <forums@zimbra.com> to=<me@mydomain.com> proto=ESMTP helo=<web3.zimbra.com>

    because of that I didnt receive an important annoucement about this 0-day. And I cant recover my regular username's password I've used for 8+ years.

    please remedy.

    apparently they do now, 36 hours after I posted.

    thanks for fixing this basic infrastructure requirement.
