User Story: As a user, I want my email to be automatically sent when it is in my outbox. In order to do this, my phone should check periodically to determine if it is has a data connection. When the connection is detected all the email in my outbox should be sent. Assumption: Interval or mechanism for a user set interval to be determined by UX. If a user set interval is desired an additional user story will be created. Acceptance Criteria: 1. The email application wakes at a specified interval and checks for a data connection 2. The interval should be determined based upon UX input or a mechanism whereby it can be set by the user. 3. If a data connection is detected, the emails the email application will attempt to send the messages 4. Once an email is sent successfully it is removed from the outbox 5. Unsent emails and emails with send errors should remain in the outbox. 6. Errors should be handled as per UX guidelines TBD.

Hey Juwei, In the Outbox Spec, you mention that the default time interval for sending outbox messages should "align to the data check for new messages." Do you want this to always match, even if the "check for new messages" sync interval is set to "Manually"? Or do you want the outbox to always try to sync at some interval even if the user has "Manually" chosen?

Hmm I know your concern. But I still think it's better to keep these two interval times align to each other... otherwise we probably will sync the data sneakily in the background that users might want save their data usage at the moment.

Clarifying the thread above: In this iteration, timed background send will occur only when incoming mails would be synced. In other words, if they've set "5 minutes" as the e-mail interval to sync, we will also check the outbox every 5 minutes. If they set "manually" as the sync interval, it will _not_ attempt to send outbox messages until/unless they do it manually.

Resolved in bug 921050.

Verified Fixed - Emails are immediately sent when they enter the Outbox. If the user lacks an internet connection, upon regaining connection, the email app will eventually automatically send the message as long as the email app is open and in the background.

Please ignore comment 6. Cannot verify because of number 6 in comment 0. Messages that couldn't be sent because of an error are showing the wrong icon in the Outbox. Please see bug 1064509
