Exchange 5.5 IMS queue filled with not valid originators

Hello,

Our Exchange 5.5 IMS outgoing queue is filled with not valid originators.  We used to get filled with blank originators which was fine, but right now we get with a lot of outside company domain originators.

Please Help!!!

Thanks

Possibly some spammers were using your server as an Open Relay. Good news is that you have banned them.

Can we do anything to abort them even from appearing in IMS queue?
