Hi, Am using Exchange server (Small Buisness server 2003 sp2) A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. Contact your administrator. <ourservername.ourdomainname.com #5.3.5> How to solve this issue Gowrishankar@ndcindia.com

Hi Gowrishankar, The NDR is typically an indication of mail-looping situation. This means that the server is configured to loop mail back to itself(go to SMTP Virtual server proprty--Delivery--Advance delivery--smarthost). If you have multiple SMTP virtual servers configured on your Exchange server, ensure that they are serving unique incoming ports. Also, to avoid looping between local SMTP virtual servers, ensure that the outgoing SMTP port configuration is valid. If you have SMTP connector then please check the configuration there as well to mitigate any loop situation. Regards, Pushkal MishrA

I've send you a test email, also check if you've any internal MX record?Regards, Pushkal MishrA
