Hi Julian

Thanks for your attention. Now it is been solved. I had wrongly mentioned the IP address of mail server. Now it is working. Thank you once again.

One more query. How can I send oracle error messages to my mail id, how can i automate it. like whenever oracle writes a messages to alert files/log/trace files, It should be mailed to dba mail id's.

Thanks once again.

Regards
Nagesh
