+* **Automatically retagging the database (e.g., when upgrading versions)**
+
+ Certain versions of notmuch include new automatic tags (for example, between
+ 0.3 and 0.10, automatic tagging of signed and encrypted messages was added).
+ However, for users running with databases created in older versions of
+ notmuch, these tags are missing in pre-existing messages and need to be
+ added. One way to do this is as follows:
+
+ $ notmuch dump ~/out.nm
+ $ mv ~/Mail/.notmuch ~/.notmuch.bak
+ $ notmuch new
+ $ notmuch tag -inbox -unread '*'
+ $ notmuch restore --accumulate ~/out.nm
+
+ At this point, one should run a sanity check on the tags, and if everything
+ has merged correctly, the ~/.notmuch.bak directory is expendable, as is
+ ~/out.nm.
+
+* **Dealing with mbox and other formats**
+
+ notmuch by itself is unable to handle non-maildir mail archives. One tool
+ to solve this is called mb2md. Assuming an mbox in ~/test.mbox and ones
+ mail archives to be in ~/Mail, an invocation would look like
+
+ $ mb2md -s ~/test.mbox -d ~/Mail/mynewmaildirname
+
+ Note that specifying the paths for -s and -d is necessary. This will create
+ a new maildir in ~/Mail/mynewmaildirname from the mbox at ~/test.mbox.
+
+ Often the formats are more convoluted, however. Many lists provide an
+ almost-but-not-quite-mbox format that mailman produces, as can be seen, for
+ example, [here](http://lists.xapian.org/pipermail/xapian-devel/). These
+ files can be converted with some degree of success to mbox using the script
+ found
+ [here](http://www.hermann-uwe.de/blog/converting-mailman-gzipd-text-archive-files-to-proper-mbox-files),
+ and from mbox to maildir as above.
+
+ However, many of these lists also have a gmane version, which, where it
+ exists, achieves far better results than dealing with the messy mailman
+ output. Using the instructions from [Gmane's
+ site](http://gmane.org/export.php), we can download an mbox file, which we
+ can then convert to maildir using mb2md or other utility.
