    [1.0/1.1] Error in Mail Sending

    I am trying to send an email in a domain using c# but there is this error message that the transport cannot find the server.

    They gave me the username as DOMAINNAME/USERNAME and the mail server as 19.4.2.90 and I just don't know why or where the cause of the error is.

    Can anybody help? Because this application have to go online latest Monday.
    I am in a lot of pressure.

    Some actual code, and the *actual* error/offending lines would help.

    If Apple fixes security flaws, they are heralded as proactive. If Microsoft fixes a security flaw, they finally got around to fixing their buggy OS.

    Did you try pinging the mail server? Also the code will be useful - Jennifer

    If the smtp server security is set to only send emails from verified IP addresses you will be blocked.

    C# - .NET 1.1 / .NET 2.0
