User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20040913 Firefox/0.10 Several incoming messages from various sources do not have accurate dates in the headers, which seems to be what is used for sorting when sort by date is selected. When new messages come in w/ older than current date, they are placed further back in inbox, mixed in with genuine old messages. Using sort by order recieved fixes this problem for the inbox, however then when moving messages between folders, these messages always appear at the bottom, rather than in the order by date (which is to be expected, I suppose). I have used other email clients (notably outlook) which seem to handle this without problems; i.e. new messages do not appear mixed in with older messages. Reproducible: Always Steps to Reproduce: 1. Set inbox to Sort by date & get new mail 2. New mail with wrong date information is mixed with genuine old mail 3. Move messages to subfolder, with a newer message being moved before an older message Actual Results: The inbox is correctly ordered, however the subfolders and/or any folder where messages have been moved to place the moved message at the bottom due to being sorted by order recieved. Expected Results: Similar behavior to Outlook, where incoming messages appear in the correct order (apparently even if date is forged), and yet when moving messages between folders the order is maintained. No need to use "order recieved" for sorting. I do not know the exact technical reason for this behavior, and it would more be an enhancement of the current sorting methods.
