    Hi,

    we are unable to send messages to one domain members. I see - 54 5.7.1 Delivery not authorized 1. People on other side say they even does not see our messages to be comming. They also use Exchange. 

    Single domain, single forest, single Exchange 2010 server.

    I used nslookup to find MX record and tryed to telnet to the smtp, and it works fine. But why messages are not delivered? How could I troubleshoot this?

    please help,
    thank you,
    n

    Hello,

    Please contact that domain administrator to check if your server ip is in blacklist.

    Please check smtp log and post it here.

    Best Regards,

    Lisa

    This error can  occur if an Exchange 2010 transport rule rejects a message because the message matched conditions that are configured on the transport rule.

    Refer the below article for your reference

    http://technet.microsoft.com/en-us/library/bb232118.aspx

    The remote server might have other rules defined that are rejecting your message

    Try to telnet from your exchange server to  host ip holding mx record  of the remote domain

    We do not have Transport rules,

    I tryed to telnet to remote MX address and it works fine.

    Should remote exchange server check Transport rules also?

    and if they say they are fine? is anything I can troubleshoot on my side?

    Enable logging on the send connector, should give you more info, may have enough to say the issue is with the remote host.

    they say:

    Diagnostic information for administrators:
    Generating server: IS OUR INTERNAL FQDN.

    And if thier server checks for IP of this FQDN they can not resolve this.

    Is any way to change this - Generating server: to point to our MX?

    thank you,

    Can you post the full NDR?

    Did you check the Send Connector logs?

    I assume you have your PTR record setup? Check on MX toolbox

    How was you connecting, was this send connector log for the NDR?

    Seems like that ISP in Lithuania is not allowing your server to send to it.

    That IP 195.182.66.20 belong to an ISP, which is not accepting your connection, so I would contact them 1st, do you use the below ISP?

    Do you use a smart host or DNS lookups?

    ISP of this IP [?]: State Enterprise Infostruktura 
Organization: Centrine Projektu Valdymo Agentura

    Well that IP is not accepting, ask them why?  Ask them to check their logs
