    How do I configure MailEnable to use a fully-qualified host name in the SMTP HELO command?

    My email users are getting the following error message:

    Message delivery has been delayed to the following recipients:
    Recipient: [SMTP:user@domain.com]
    Reason: Remote SMTP Server Returned: 504 5.5.2 <hostname>: Helo command rejected: need fully-qualified hostname
    421 4.4.2 host.domain.com Error: timeout exceeded

    Anyone know how to fix this?

    Anybody any info on this one? I have the same problem. This only seems to happen to one specific domain, however on my linux boxes no problems.
