    Default Outgoing mail seen as spam.

    Hi All,
    I have installed the latest version of Zimbra and all is well.
    The only problem I am having is that external mail seems to be returned rejected
    by mail servers seeing it as spam.
    The server is behind a NAT Firewall (untangle) , our external mail is hosted (POP)
    by a ISP.
    It appears that the mail servers don't trust the sending IP?

    Any help will be appreciated, I am not a network guru, so simple explanations would be welcome!

    Thanks
    Rory

    You may want to add an "spf" record to your DNS server if you don't already have one. If you do have one, you may want to double check your "SPF" record making sure you declare where mail is allowed to be sent from etc. Hope this helps

    What are the error messages you are seeing? Rejected mail could be caused by many things.

    If you are on a dynamic IP and/or don't have a reverse DNS then you'll most likely have problems.

    Your best option may be to relay outgoing mail through your ISPs mail server.
