As described here:

http://live.gnome.org/Tracker/Documentation/Examples/SPARQL/Email#Storage

To get a good scheme for forming URLs for IMAP, read RFC 5092. 

The FETCH command in IMAP explains how to use sections at page 55. For a
URL scheme for POP read RFC 2384. Avoid inventing your own URL scheme.
You want to use these URLs for the value of  nie:url  in RDF. You can
also use them for the subjects of your resources, which is what I will
do in the examples that follow.
