    Default e-mail rejected FQHN

    Our e-mails to a Zimbra client keep getting rejected. below is the log from Zimbra. We checked and all our settings seem to be correct, and our e-mails get delivered fine to most e-mail servers. Any ideas?

    Oct 22 13:05:23 zimbra postfix/smtpd[19586]: connect from[]
    Oct 22 13:05:24 zimbra postfix/smtpd[19586]: NOQUEUE: reject: RCPT from[]: 504 5.5.2 <ds5029>: Helo command rejected: need fully-qualified hostname; from=<> to=<> proto=ESMTP helo=<ds5029>

    your client is presenting itself to the server as ds5029, but due to the AntiSpam measures in place it requires the client to have a FQDN (Fully Qualified Domain Name) eg.
