Hi Stef,
Thanks for your response. The email address I am using is working fine as I was able to send or receive emails. I guess the issue seems to be something related to hosting server that is used to send the email from wordpress. So I tried using an SMTP plugin (WP Mail SMTP) and used Mailgun provider. This solved my issues and all email notifications are working fine now.
Thanks,
Ashok
