This is the name that will be used in outgoing messages. Here you can configure your main identity. These settings control everything related to sending mail. This setting is intended as safety mechanism to limit the number of Push connections regardless of how many folders are configured to be checked via Push. This can quickly add up and exceed the number of concurrent connections your mail server allows you to establish. K-9 Mail needs to establish one connection for each folder that is checked via Push.
Otherwise it will only download new messages.
When this is enabled K-9 Mail will do a full folder synchronization after establishing a Push connection. If you’re not familiar with the details of the IMAP protocol you shouldn’t change any of these settings. K-9 Mail supports some advanced settings for IMAP accounts. Please see the section Incoming Server Settings on the page Add Account for the available settings. Note: This setting is only available for IMAP accounts. K-9 Mail currently doesn’t support that functionality. Note: Some clients can display messages that are marked for deletion and allow you to remove that flag, undeleting them. Here you can control when they are actually deleted (expunged). Normally, messages on the server are simply marked for deletion.
Note: This setting is only available for IMAP accounts, because it’s the only account type that supports Push. To learn more about this, read the page Folders. Push foldersĬontrol whether to push all, 1st class, 2nd class or no folders. Poll foldersĬontrol whether to poll all, 1st Class, 2nd Class or no folders at all. Folder poll frequencyĬontrol the poll frequency from never up to 24 hours. When viewing messages larger than this value you will see a button saying Download complete message that allows you to download the rest of the message. Set a limit on how much of a message is downloaded during synchronization. That means you won’t be able to manually fetch messages older than specified here. Note: Currently, pressing Load up to XX more in the message list doesn’t override this setting. During synchronization K-9 Mail will remove previously downloaded messages that fall outside that range from the device (but not the server). If you set this to anything other than any time (no limit) K-9 Mail will only download messages that are younger than a certain time span. This is no hard limit and you can download more messages by pressing Load up to XX more at the end of the message list. When new messages are downloaded older messages will be deleted from the device (but not from the server). Specify the number of messages that will be downloaded for a folder. These settings control how and when mail is fetched for this account.
Independent of what you select here, you can always select Mark as read or Mark unread from the menu when viewing a message. Uncheck this to not mark messages as read when you open them.
