Best options for junk email filtering
 

My company has our exchange server that forwards our email to our 6700's. The problem is that 5 out of 10 emails I get are spam. Is their a program that will eradicate the email on the device? The server side is already using a filter (it must suck or we are getting pummeled!!). Any suggestions??

Can't say if it's any good but you can try Pocket SpamFilter.

If you don't want a software solution on your device, you could maybe forward your exchange mail to another host exchange server that has better SPAM control and sync to that instead.
