  • Problems sending Emails

    Hi,

    We have a problem sending email to a particular domain. The error we get is

    Connected to 212.227.15.134 but greeting failed.
    Remote host said: 550 RBL rejection: local dynamic IP address 203.43.85.129


    I have a feeling that its more to do with recipient end and not from our end but I just wanted to confirm what i think is right.

    We do not have any problems sending to other domains. its only just this domain.

    Could anyone please throw some info on this.

    Thanks

    Raman

    The good news is that it does not look like your server is blacklisted.

    http://dnsbl.info/lookup.asp?IP=203.43.85.129

    However, the message "greeting failed" is what you need to look into. My guess is that your Reverse DNS for the mail server is incorrect. A quick check shows us:

    c:\> nslookup 203.43.85.129
    Name: mail.sge.com
    Address: 203.43.85.129

    c:\> telnet mail.sge.com 25
    220 sge.com ESMTP

    The name returned in the SMTP session does not match the reverse DNS. Hence, "greeting failed".

    The next part also leads me to a reason for the rejection. "local dynamic IP address" It seems that the server might think your IP is dynamic, and not statically assigned by your ISP. You may need to contact the admin of the mail server and have them whitelist your mail server.

      Thanks for the quick response. Just with the last answer re. whitelisting, you mean contacting the other end and getting them to whitelist our doamin
