File and Image Search
Can't find the document or photo? No worries! Postbox's Document and Image Search provides fast access to files hiding within your email messages — no more digging through email messages to find what you need!
And once you've found what you're looking for, Postbox lets you save or send the file with just one click.
File messages without touching your mouse using Quick Move. Just type "v" and the first few letters of the target folder's name, and the message will file to your auto-completed selection.
The Quick Move panel defaults to the last used folder for even faster filing.
