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.

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.
Merged from branch issue143 @ revision 426:
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.
Can be set to -NONE-, so that no folder is automatically expanded.
Defaults to Inbox, which is like the default behavior of the core
Android Email.
Fails to move the automatically opened folder to the top of the
screen. This needs more work.
The already selected folder should be highlighted (or otherwise
indicated) in the ChooseFolder Activity. This needs more work.
Accounts: Option menu->Check mail = check mail in all
folders of all accounts
Accounts: Context (long-press on account) menu->Check mail = check mail
in all folders of this account
Folder/Message List: Option menu->Check mail = check mail in all
folders of this account
Folder/Message List: Contet (long-press on folder) menu->Check mail = check mail in this
folder*
*All "Check mail" options, except for the long-press on an individual
folder, respect the normal synchronization class settings.
Eliminate all Refresh menu items.
Add progress indicators to Accounts activity. Indeterminite progress
indicator while email checking is in progress. Determinite progress
indicator while fetching unread counts.

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.
