    I have a exchange 2003 box and i cannot send mail to verizonwireless.com from our domain resourcelabel.com

    I have added a reverse dns ptr record and a spf record and still no luck :(

    When using SMTPDiag i get this error: smtpdiag [email protected] [email protected] /v

    Connecting to mars.verizonwirelss.com [162.115.227.108] on port 25.
    Received:
    554 venus.verizonwireless.com

    Error: Expected “220” Server is not accepting connections. Failed to submit mail to mars.verizonwireless.com

    when enabling logging in exchange it gives the error:
    source: msExchangeTransport
    Event ID: 4006
    Message delivery to the host ‘162.115.227.108’ failed while delivering to the remote domain Verizonwireless.com for the folowing reason: An SMPT protocol error occurred

    please helppp!!
