Sounds like it's working as designed. Sent mail and message deletions don't reconcile from handheld to desktop for all email services.
Who is your email provider?
No idea what that is. How do you access your email? Is it via POP3?
The link I provided above shows the reconciliation features for various email providers.
It wouldn't be listed. It comes under "Post Office Protocol 3 (POP3)"
Also note, deletions of mail from BB to server, take a while to actually happen.
And no, sent mail from the BB will not appear in sent mail on your server.
