Samsung Captivate (Galaxy S)

Is there a way to change the settings so that a copy of any emails I send from the phone is automatically saved in the sent folder on my computer? My blackberry does this & I love that about the blackberry! At the end of the day I get on my laptop & filter my sent emails to the appropriate folders. The captivate however doesn't save a copy to my sent folder other than the one on the phone itself, that or I just can't find the setting to enable that. Any suggestions?
