Summary

3836

Applies To

  • ERP System: ( Oracle, SAP, Peoplesoft)
  • MarkView Version: (All Versions.)

Behavior

  • Mail gateway is reporting the following error: 
    UNABLE TO RESOLVE IP ADDRESS FOR MAIL SERVER SPECIFIED
Proxy is password protected
'Error in initiating conversation with Mail Server'
SMTP, Port 25, <mailserver>.domain, UID: <mailgw>
Unable to Resolve ip address for mail server specified.

Known Causes

  • The mail server (Exchange/SMTP Server) is configured to use security to verify the sender's ip address.

Resolution

  • If the SQL*Flow Mail Gateway machine is not setup in DNS/DHCP, the reverse lookup failed of the SQL*Flow Mail Gateway server ip address fails, and the mail server denies access to SMTP.

    You can test this by telnetting to the mail server.
    From the command (DOS) prompt:
    TYPE: telnet <mailserver> 25
    (Normally, the smtp server is configured to listen on port 25)

    RESULT: You should receive the mail server message

    TYPE: HELO
    RESULT: received error message - not authorized to telnet helo
