I use T-Mobile BWC. It gives me the option to bcc all sent mails to my email address. I have then created a rule on the outlook client to read the header for any email with
![[email address]](http://www.blackberryforums.com/?emailimage=ab9d8ae953962ef139a40c33a485b4a2)
and move it to the sent items. The only drawback of this is that whenever I send out a mail, I receive an extra mail on my blackberry device (which is also good, I know my mail has gone

).
Hope this helps
