Iseries assistance dealing w/ spam

I read today on one of the trade sites about using the Iseries mail capability. 
Where I work, of course there is a major spam problem. As well, they are 
targeting all mail that an employee gets or sends. They wish to restrict 
personal usage. So what they have in place, is cumbersome. Using Exchange and a 
spam product everything that comes in is held if it is new. So the employee has 
to send an emaiil to spam-approval to accept this email. From then on, it is 
supposed to let them in again, altho this doesn't always work. 
1. Is there a way for a Iseries program to get to this data and to perform the 
necessary file maintenance tasks to assure there is a correct application 
process going on?
Thank you for any input,
Jay
