• Adds a new option: --cleanup . When cleanup is enabled on restores, GYB will check each message and confirm that the message has a valid From:, Message-ID: and Date: header. If the headers are missing or are not in the right format, GYB will modify them. This should solve #342 where restored messages are going to the Spam folder because they did not have valid messages. Note that this modifies the restored message and cannot be undone.
• Additional options --cleanup-from and --cleanup-date allow you to specify a replacement header value when --cleanup is specified and GYB finds the header is not valid. For example, --cleanup --cleanup-from "Nobody <nobody@nowhere.com>" --cleanup-date "Sat, 22 Apr 2006 11:28:00 +0000"
