    Default SMTP Authentication

    I have Zimbra setup and running. Everything works fine except for the remote users.
    I have some users outside the LAN connected via ADSL. I need to configure outlook to send email through the zimbra mail server.
    Mynetworks are for local networks for securityu reasons.
    i need to configure in outlook smtp : zimbra.domain.com, with authentication .

    configuration is:

    zmprov gs zimbra.domain.com |grep Auth
    zimbraMtaAuthEnabled: TRUE
    zimbraMtaAuthHost: zimbra.domain.com
    zimbraMtaAuthURL: http://zimbra.domain.com/service/soap/
    zimbraMtaTlsAuthOnly: TRUE

    zmprov gs pinus.dgrf.min-agricultura.pt |grep Mode
    zimbraMailMode: https

    The idea is to configure in outlook to have
    My outgoing server (SMTP) requires authentication
    Use same settings as my incoming mail server

    I have in the server:
    Enable authentication
    TLS authentication only

    but is not working

    Any idea?

    Why do you not believe the answer I've already given you? Perhaps I'm not explaining myself clearly enough?

    Hi
    sorry but do know an application called msmtp it is a smtp client and it send mail
    from from any computer that it is installed on using any open mail server to send mail and if there is no authentication it will send alot of mails under my nose and i wont know until my server is blacklisted,
    if you dont beleive me give me a mail server that doesnt have smtp authentication enabled on it and i will send you a mail from it

    You are testing msmtp on your server and you have the 'client' installed on your LAN?

    .... and the question was, you tried this from your LAN?

    Just for clarification, it's not an SMTP client it's a normal mail client just the same as Outlook, Thunderbird etc. they are normal mail clients that send through Port 25.

    Did you actually check the link I gave you for testing if your server is an Open Relay? What were the results?
    Regards

    Well, of course you do. Your system is in the Trusted Network and anyone in YOUR Trusted Network can send mail to the outside world without authentication - they are the only people that can send and that's why, when an external user authenticates (he becomes part of the Trusted Network because he's connected to your server on the LAN) he can send mail outside your network.
