Database Test Mail is Failed

Hi All,

I have configured database Mail in Sql server 2012 but couldn't able to send the test mail.

1) Enabled "broker"

2) Enabled "Database Mail XPs"

3) Selected "Public"

4) Tried both Basic and Anonymous authentication respectively

5) Account has sysadmin rights

When I verified select *from sysmail_allitems from msdb, every time it is moving from unsent, retrying and finally failed

Please find the below error from "Veiw Database Mail Logs"

Message
The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 9 (2014-07-15T15:02:50). Exception Message: Cannot send mails to mail server. (Failure sending mail.).
)

Please suggest and kindly let me know if you need any further details on this.

Thanks for your time and support

Kalyan
