Authentication SMTP to IP's SMTP - OR - How Does SBS's SMTP send a User Name / Password?

    Hello Fellow Travelers,

    I have run into quit a challenge with SBS and authenticating its
    SMTP server with that of an IP's.

    Everything was working fine until Cox sold to Suddenlink. If I
    am understanding it correctly, Suddenlink has implemented both reverse DNS
    lookup for e-mail and the 'My server requires authentication' (meaning their
    SMTP server) to send e-mail.

    Yes, you guessed it; in the past I have sent mail using my SMTP
    server via the DNS lookup and received mail from the IP using POP. This
    still works well until I run into a reverse DNS lookup; the e-mail is
    bounced back. I figured I could overcome this by simply using Suddenlink's
    mail server to both send and receive e-mail.

    This has been 'no picnic' to change over. Yes, just changing
    the way e-mail is handled with SBS's 'Configure E-mail and Internet
    Connection Wizard' works great with Internet providers that don't require
    authentication, but Suddenlink requires authentication to use their SMTP
    server. How does one authenticate the Small Business Server's SMTP with
    another SMTP server?

    Thanks in advance for any help you can give.

    Regards,

    On the Properties of the SMTP connector where you enter the smarthost,
    go to the Advanced tab and click Outbound Security, then enter either
    basic authentication details or TLS according to the ISP's requirements.
