    Default SMTP error

    I tried to send email using thunderbird, but it prompt an error as below :

    "Sending of message failed.
    An error occurred sending mail: Unable to authenticate to SMTP server mail.noblehouse-labuan.com. It does not support authentication (SMTP-AUTH) but you have chosen to use authentication. Uncheck 'Use name and password' for that server or contact your service provider."

    how can i fix this problem?my secure pop3 is not a problem

    Seems you have " My server requires authentication " clicked. Remove that. Pretty interesting , allows relaying.

    i had tried what you suggested, but i get the error below

    "An (SMTP) error occurred while sending mail. The server responded: Transaction failed"

    "Sending of message failed.
    The message could not be sent because the connection to SMTP server mail.noblehouse-labuan.com was lost in the middle of the transaction. Try again or contact your network administrator."

    Seems to me to be a firewall issue. I have seen couple of times. Can you share /var/log/zimbra.log entry for this email transaction please ?
