pass successfully with maildir enabled as the default mailbox storage format.

If you want to experience maildir, you need to set the string pref

"mail.serverDefaultStoreContractID" to "@mozilla.org/msgstore/maildirstore;1".

to work with maildir so as to avoid any dataloss that might occur.

There are still a few issues left to be addressed with maildir implementation. But a number of

issues were addressed. So far,

* Sub folder directories are created at the expected place now. See [https://bugzilla.mozilla.org/show_bug.cgi?id=1017939 bug 1017939]

The major issues left with maildir are that of IMAP.

* Move to maildir local folders sometimes fail. See [https://bugzilla.mozilla.org/show_bug.cgi?id=859011 bug 859011], [https://bugzilla.mozilla.org/show_bug.cgi?id=1215722 bug 1215722].

* Rename of IMAP folders is in progress. See [https://bugzilla.mozilla.org/show_bug.cgi?id=857436 bug 857436]

Please don't use CopyService for any copy operations in the source code if you are using maildir. As of now,

we haven't addressed this bit and copying using CopyService results in process crash.
