Thanks to Google.
I have found Microsoft Technet article and came to know that Junk filter can be managed by EMS
http://technet.microsoft.com/en-us/library/dd979780(v=exchg.141).aspx
I have checked the Junk filter for that user and the user was added many domains and email address. I am unable to view all address, again i took help from google and found wonder full article. we can use the below command to view all address on single page.
(Get-MailboxJunkEmailConfiguration myidentity).BlockedSendersAndDomains
Here i don't see the domains and address so i added manually by using the below command
$Temp = Get-MailboxJunkEmailConfiguration "Michele Martin"
$Temp.TrustedSendersAndDomains += "contoso.com","fabrikam.com"
$Temp.BlockedSendersAndDomains += "jane@fourthcoffee.com"
Set-MailboxJunkEmailConfiguration -Identity "Michele Martin" -TrustedSendersAndDomains $Temp.TrustedSendersAndDomains -BlockedSendersAndDomains $Temp.BlockedSendersAndDomains
