    Unanswered: ORA-20001: 421 Service not available

    Hello All,

    From Oracle 8.1.7, I am trying to send the mail. I ensured that JServer and JVM are installed.

    When I am trying to connect to the mail server and getting the following error. The mail server is Microsoft Exchange Server.

    ORA-20001: 421 Service not available

    I understand this is because SMTP service is not available.
    I am sure that Microsoft Exchange Server's by default uses SMTP service.
    Then where could be the problem? Do you think that SMTP service is not available in Oracle 8.1.7?

    Would appreciate the immediate response.

    Thank you,
