Polling a folder will re-scan the entire folder for changes, and transfer over all new messages (or the latest N messages as per the dir limit settings). For most people, there is no need to poll often. I would suggest no more often than every 6 hours, and 24 hours should be fine. If the IMAP server supports PUSH, then any new messages that arrive while you have an active internet connection will be "pushed" to the device. This means that if you lose connection, any messages that arrive during that time will not load until the next poll or manual sync. If the device is a tablet without a cellular connection, Android may decide to disable the wifi radio while the device is not in use. This will cause loss of PUSH and necessitate polling / manual sync. PUSH does, however, keep an open connection, which may cause the wifi radio to never go to sleep. My overall suggestion is set polling to whatever interval you check your email at (i.e. if you only check your email once a day, set it to 24 hours). Also consider disabling PUSH, as it may keep the wifi radio from sleeping and cause the battery drain. --Sean -- -- You received this message because you are subscribed to the K-9 Mail Users List.
