Dear erman,

Issue is fixed by adding smtp server ip in /etc/hosts file in DEV instance.But in PROD,we dont have this smtp server entry in /etc/hosts file.Not sure how it is working in prod without this entry and how it is not working in DEV

can you please provide your ideas

Thank you

Aha..

Maybe in PROD, you have a DNS configured.. So PROD could resolve the name using DNS..
When you have a proper DNS, you don't need to write down the ip and host information of all the servers to your /etc/hosts file..

Thanks erman for the updates.

In prod also,we have all the application and database nodes IP's listed in /etc/hosts except smtp servers IP.How can we check if it is using  DNS

[ErmanArslansOracleBlog]

you can check /etc/resolv.conf file.
also you can query the dns using nslookup <ip_address>
