Help Can I turn off saving sent emails


Hi, I tried to search for this, and I am sure it's in here somewhere, bu I can't find it. I just switched from BB to Droid Incredible and so far I like it. But I need to turn off the functionality of it saving (or syncing) my sent emails. I send a lot of emails for work and when I send them from my pc or the DINC they are being saved on the DINC. Can I stop this from happening? It's cool if it wants to save the emails I send from handheld, but not the PC. Thanks
