Global or per-repository option utime_from_message tells OfflineIMAP to set file modification time of messages pushed from one repository to another basing on the message's "Date" header. This is useful if you are doing some processing/finding on your Maildir (for example, finding messages older than 3 months), without parsing each file/message content.
