. HTMLized version of plain text email is not loaded up as a MIME part of the message anymore. We use a custom seperate variable in the text body class.
. Free up memory as we go in MessagingController.synchronizeMailboxSynchronous()
. IMAP: We only do a partial fetch of the text body of large messages during background sync. This allow for faster syncs and avoid expensive parsing that lead to OutOfMemoryError
When no accounts are set for automatic sync, the MailService is
stopped. When the MailService is stopped, the Android platform is
given greater leeway in killing the entire K9 process in order to free
system resources.
Fix POP3 deletes. Verizon uses - in their POP3 UIDs, and K9 was
assuming that only Local UIDs have -. Removed that assumption. Also,
after issuing DELE on POP3 connection, need to also issue a QUIT. The
delete code in MessagingController now closes the folder after
deleting a message, which will slow down IMAP deletes, but also
conserve connections, so is probably a net benefit.
synchronization could happen if an Exception was thrown while parsing
an untagged response without using executeSimpleCommand. For
instance, while doing a fetch. Once synchronization was lost, later
commands would fail in surprising ways. One manifestation of such
failures was spontaneously emptying of folders when search results
were not returned properly. The new code makes sure to only accept OK
responses with the tag of the command, and discards the untagged
responses from previous command.
Issue 252
394: Replace code change lost with move of DAmail MailService.java to
K-9. Eliminate the stopSelfs. Without the stopSelfs, the Service
remains active and the Android platform is far less likely to kill the
process, although not absolutely forbidden from doing so. Better will
be to implement the full BroadcastReceiver methodology referred to in
Issue 394, which would allow replacing the stopSelfs, which would make
K-9 a better good citizen.
252: Fix logic for raising and canceling notifications based on number
of new unread messages and total unread messages.

Handle untagged EXISTS messages at any time. Should increase
synchronization speed and accuracy.
Handle IMAP servers that send a NIL where a literal is normally.
Avoids failure to sync when folder contains certain messages.
Throw Exception if folder message count is less than 0, avoiding
accidentally emptying a folder.
Issue 192
Do not remove markers for deleted messages, even if the corresponding
remote message is not returned by the remote store. The remote
message may not be returned simply because the query did not encompass
it on this run. If the account's delete policy is set to "Do not
delete from server", or the delete hasn't succeeded before a folder
refresh, a message for which the deleted marker has been removed can
errorneously reappear.
This will lead to the local store eventually having a large number of
deleted message markers. In the long term, we'll need a way to manage
and possibly automatically remove them.

Complete replacement for SharedPreferences. Uses SQLite database
stored in application's databases folder.
Will load from legacy preferences if DB-backed preferences are empty.
Editor conforms to atomic commit contract.
Hardening of POP3 and SMTP communication:
SMTP: Decrement failure counter when no possible message send
occurred. This way, K-9 will only stop attempting to send messages
for which a possible successful send occurred, but K-9 could not
detect. Any message that is known to have completely failed to send
will be reattempted indefinitely.
POP3: Some reworking of Exception handling. Also, if it is not
possible to get a "message number" for the UID of the message that is
being deleted, conclude that the message has already been deleted on
the server. Mark this as a permanent error, so that it gets removed
from the pending actions queue.
MessagingController: Look for the permanentFailure flag on the
MessagingException, and if a pending action raised a permanent
failure, remove the pending action from the queue so that it will not
be re-attempted nor block later requests.
Significant hardening of the email sending process.
A given message in the Outbox is only attempted to be sent 5 times.
Once the threshold is reached, the message is flagged. asses through
the Outbox skip flagged messages. The message can be tried again by
manually unflagging. When any messages are flagged during a pass
through the Outbox, K-9 raises a notification with a fast flashing red
LED, alerting the user to the failure to send. A note is also placed
in the K9mail-errors.
The read timeout on SMTP connections has been changed to 300000ms (5
minutes)
The send attempt counter is kept in memory, not stored with the
message, so a phone or application restart will clear the counters,
but not the flagged state. As the intent of this revision is to avoid
runaway message sending, this is deemed to be acceptable for now.
The moving of messages from the Outbox to the Sent folder has been
changed to an atomic move.
Extra error checking has been added to the SMTP communication code.
The flashing LED may be excessive.
Provide preference for which folder is automatically expanded when
entering the Folder/Message list.

*All "Check mail" options, except for the long-press on an individual

One change of my own, putting the actual folders name outside the
parentheses, and the functional/special name inside the parentheses.
Copy now copied body (but attachments might not work right).
Move is now reliable (needed to open the destination folder), and
leaves a placeHolder message behind in the source folder so that
messages are not resynced.
3.
Each remote Store (IMAP, POP3, WebDAV) can provide indications to the
higher level classes as to whether copy and move are implemented.
Currently, copy and move are only provided by ImapStore.java. When
the facilities are not available, the user interface suppresses the
menu options.
The available destination folders can be configured using folder
classes.
Copy results in null message bodies in the destination copy of the
message until the next sync. This is a problem that occurred with
deletes previously, and is likely a fault with the copyMessages method
of LocalStore.java.
Utilizes a modified version of the ChooseFolder.java Activity that
debuachedsloth contributed in a patch attached to Issue 285 on 16 Feb
2008.
All messages in all folders that were sent from the email address
associated with the account display the recipient, preceeded by To:,
instead of the sender.
Puts quotes around username and password for IMAP authentication.
Also, if authentication fails, closes the connection so that it will
be retried. Otherwise, there is no way to fix the problem, say, by
changing the password in the Incoming Settings.
ConcurrentHashMap seems to serialize as a HashMap. Not sure why or
how.
This change has re-enabled the saving of the unread counts during an
orientation change, giving somewhat fast response. If it fails again,
just comment out the block of code.
Provide two options for each Account:
Compact (which VACUUMs the accounts and prunes recreatable
attachments)
Clear all data (danger!) (which wipes all messages and attachments in
the account, except placeholder deleted messages)
Displays a Toast when the Compact or Clear is queued, and another
Toast with the shrinkage results.
(Also, a small change to increase probability of seeing messages after
a sync, by setting the needsRefresh on all folders when a sync is done.)

Push unread message counting into the background.
Should increase startup performance and reduce black-screens-of-death

Also, updates the per-account unread message count when email account
is finished synchronizing.
Note: Notifications are displayed after all accounts are sync'ed but are delayed to be 1sec. apart
TODO: Display notifications at the end of each individual sync
folders are sorted first by subject, then by date. Subject sorting is
case insensitive and disregards leading re:, fw: and fwd: prefixes.
Threading can be toggled via the T hotkey or the option menu.
The icons could use improvement.
Threading state is maintained during a run of K-9, among all

Re-enable instant deletes in MessageView
Deleted message suppression should be generalized into a flag cache,
serving Seen, Flagged, and Answered flags, as well.
Copy message to Trash still needs work, so that no duplicates are ever
visible and server-sync is more clean. This will be especially
important, as the same code will be needed for the future "message
copy/move" facility.
Account settings) for scrolling the navigation buttons with the
message, or keeping the buttons on screen. Scrolling mode can be
automatically switched based on availability of keyboard. (Issue 197
and Issue 194)
Add ability to flag/unflag message from options menu
1) Eliminate the top row Next Message and Previous Message
2) In the bottom buttons for portrait mode, replace Reply and Forward
with Prev and Next
Justification: if you're going to be replying or forwarding, you're
about to embark on a lot of typing, anyway. Having to hit Menu
isn't an undue burden.
3) Prev goes to the adjacent *older* message, next goes to the
adjacent *newer* message
4) In the bottom buttons for landscape mode, added Prev and Next as the
outer buttons
5) Add Account option for hiding the bottom buttons when the keyboard
is available.
Also, temporarily (hopefully!) reverted the instant delete from the
MessageView because it isn't working right. The method here is slower
but safer.
date/time formats. With this change, K-9 can run on original master
or cupcake versions for the platform.
This seems like an excessive amount of code. Perhaps there is a
public API that accomplishes this work. Alternatively, the code in
MessageView.java and FolderMessageList.java should be consolidated
into a utility class used by both of the classes needing this
functionality.

hotkey G (toggle) or by long-pressing the message to bring up the
message context menu. Can be done while viewing an individual message
by using the hotkey G (toggle). To-do: add a Flag/Unflag option to a
menu in the individual message view.
Add sending the Answered flag to the IMAP server when replying to a
message. This is currently done as soon as the reply is started.
Perhaps it would be better to wait until the reply is sent, but that
would require keeping additional state with the draft. Messages to
which the user has replied are indicated with a white arrow next to
the subject.
To-do: In the MessageView, provide visual indication of Flagged and
Answered states.
approach should guarantee that the syncing never stalls just because a
single attempt exceeds the (currently 10 minute) WakeLock timeout. At
the sync frequency, K-9 will wakeup again and refresh the WakeLock for
another go at syncing. This should make synchronization much more
reliable in the face of slow or unavailable connections, in particular
ones which hit the socket read timeouts.
Also, fixed the audible notifications so that the ringtone selected
is always for one of the accounts with new unread mail.
Developers now have the option to turn on a fast-flashing LED during
synchronization in order to observe whether synchronization is
happening while the handset is apparently asleep. I think this option
would be aggravating to non-developer users. See

Automatically clean up deleted messages in Outbox (make deleted
messages destroyed); don't try to send deleted messages, destroy
messages in outbox when deleting. (Yep, the first and third items are
redundant, but will automatically clean up damaged outboxes)
Added support for default mailbox path setting if we can't automatically determine what it is.
Fixed a bug exposed by changes relating to a fix for non-relative email paths being returned.
to send the proper delete requests (delete, mark read, nothing).
Otherwise, this code will delete on the server any message deleted on
the handset, no matter option the user selects.
MessageView
Deleting a message in Trash deletes it for real (permanently)
All message operations are allowed on messages in the Outbox. Special
handling for deleting, so that the message is copied to Trash, then
copied asynchronously to the remote Trash.
Add some more items to the hotkey help
Fixed "loading more messages" to use the cleaner String.format way of doing things, and changed the corresponding entries in strings.xml.
Deleted the now-unused build_number.xml file.
Accounts are now set:
Folder display mode = All except 2nd Class
Folder sync mode = Only 1st Class
Only the Inbox is set for:
Folder sync class = 1st Class
All other folders have class set to None for sync and display
Also restored an optimization on opening local folders that I
removed. It is now optimistic, and in the normal case does not have
to make an explicit existence check
features are added to K9mail:
1) Show unread message count on each folder
2) Sum unread count of all shown folders in an account to the account display
3) Periodically check selected folders for new mail, not just Inbox
4) Don't refresh folder when opened (unless folder is empty)
5) Show date and time of last sync for each folder
6) Fix timer for automatic periodic sync (use wakelock to assure completion)
7) Optimize local folder queries (speeds up account and folder lists)
8) Show Loading... message in status bar indicating which folder is being synced
9) Eliminate redundant sync of new messages (performance enhancement)
10) Improve notification text for multiple accounts
11) Do not automatically sync folders more often than the account-specific period
12) Use user-configured date and time formats
13) Select which folders are shown, using configurable Classes
14) Select which folders are synced, using configurable Classes
15) Added context (long press) menu to folders, to provide for Refresh
and Folder Settings
16) Status light flashes purple when there are unread messages
17) Folder list more quickly eliminates display of deleted and out-of-Class folders.
18) Delete works
19) Mark all messages as read (in the folder context menu)
20) Notifications only for new unread messages
21) One minute synchronization frequency
22) Deleting an unread message decrements unread counter
23) Notifications work for POP3 accounts
24) Message deletes work for POP3 accounts
25) Explicit errors show in folder list
26) Stack traces saved to folder K9mail-errors
27) Clear pending actions (danger, for emergencies only!)
28) Delete policy in Account settings
29) DNS cache in InetAddress disabled
30) Trapped some crash-causing error conditions
31) Eliminate duplicate copies to Sent folder
32) Prevent crashes due to message listener concurrency
33) Empty Trash
34) Nuclear "Mark all messages as read" (marks all messages as read in
server-side folder, irrespective of which messages have been downloaded)
35) Forward (alternate) to allow forwarding email through other programs
36) Accept text/plain Intents to allow other programs to send email through K9mail
37) Displays Outbox sending status
38) Manual retry of outbox sending when "Refresh"ing Outbox
39) Folder error status is persisted
40) Ability to log to arbitrary file
