The mail system deletes items that are mailed without adding a recipient in the to: field of the mail. This may not be a bug but by design but if it is, it is a very bad one with severe consequences. I stumbled across this when I was playing around with the mail function and started composing a mail and attached some items to it. I casually hit SEND without adding a recipient, expecting that the items would be returned to my inventory since the mail wasn’t addressed to anyone. Imagine my surprise when the items were deleted instead of being returned. Can the developers please change this so items are not deleted but returned to inventory if no recipient is listed?
