Exchange Server 2010 Queue Viewer has many spam messages and messages that are being delayed.
In my Exchange 2010 Queue Viewer I have many messages that are listed as being sent from an internal email address, an external Source IP address, a received date and the subject indicates that it is obviously spam of some sort. Some domain users are also reporting that they are getting the "#550 #5.7.1 Your access to submit messages to this e-mail system has been rejected" bounce back emails.
This issue started about a week ago and no server or DNS settings have been changed. What can i do to stop these messages from entering the queue and get the bounceback email to be delivered to the intended recipients?
Thank you!

Glad to here from you also One more thing I forgot is,
Go to Anti spam tab and there you will find sender filter. go to its properties. click on Blocked sender tab. in the botton check the option for "Block messages with blank sender"
This will block the blank email sender (spam mail) who does not have email address.

I also made changes to the receive connector to receive SMTP only from our email filtering service.
MB Shaikh, good suggestion, however the spam issue appears to be resolved.
Thank you both!
