Hello!
I've been using Touchdown HD for a long time. I've recenty encountered a bug when it comes to forwarding attachments. Here's how to reproduce:
1. Choose and email that someone sent you with an attachment.
2. Download that attachment.
3. Forward that email with the downloaded attachment.
4. His the paperclip button to confirm you have the attachment.
4. UNCHECK "Quote original"
5. Send.
The attachment will not be included in the received email.
