We have ubuntu 12.04 server and installed sendmail to send mails from this server.
Problem:
There is some strange issue on mail server. Somehow, server not able to send email to xxx@ayolla.com
but server sends email successfully to other email ids like xxx@spaceotechnologies.com, xxx@gmail.com or xxx@yahoo.com.
Success Case: when send email to xxx@spaceotechnologies.com
