Getting "The following organization rejected your message: ESMTP" when send to certain domain. RRS feed

  • General discussion

  • Hi, We having trouble sending email to a certain domains, all sent emails will bounced back with "The following organization rejected your message: ESMTP" and the Generating server is our exchange server.  I haven contacted the other domain admin to add us on their whitelist, but they told me that its actually our own server is blocking it before it even send out, so I'm wondering how do I solve this problem?

    Here is the bounce back message:

    Delivery has failed to these recipients or distribution lists:

    user@somedomain.ca
    An error occurred while trying to deliver this message to the recipient's e-mail address. Microsoft Exchange will not try to redeliver this message for you. Please try resending this message, or provide the following diagnostic text to your system administrator.

    P.S. I have used MXToolBox to check if our IP is in blacklist, checked RTP too, everything is fine.

  • Can you up the logging on the send cinnector to verbise & see what the logs say? Do you have any cisco type firewall or any other firewall in front if exch whch has  ESMTP enabled?, if yes, disable it & test.

    Can you send via telnet?

    So everything looks fine until it target the email as Spam, I thought it was the reception's domain blocking us, but then it shows our server name.  We are using just a normal router from Linksys (WRT160n) with port forwarding port 25 for SMTP, other than that we don't have any other firewall with ESMTP.  I'm not the one who configured the exchange server, it was a company we hired long time ago, so not sure where I should look.  I'm not sure how to use Telnet to test.

    It seems to indicate the  recipients system is rejecting your email not your Exch server. Your Exch server is just generating the NDR because the remote system is not allowing it to submit that message.

    The recipients's org may have you blacklisted or be subscribed to an RBL blacklist which has you listed. Ask them to whitelist you.

    If you want to do a telnet test - here
