*I haven't done this myself, but here's some ideas for you to research.
*
*The POP3.retr() method returns a tuple, the second member of 
*which is (iirc) a
*list of lines.  You can probably safely discard the other two items.
*
*lines = pop.retr(n)[1]
*
*You need to feed a file to the email module, but saving all of 
*this to a file
*would be pointless.  The solution is the StringIO (or better 
*yet, cStringIO),
*which will convert a string into a file-like object.
*
*import cStringIO
*fakefile = cStringIO.StringIO( '\n'.join(lines) )
*
*I use '\n'.join() to convert the list of lines into a single 
*string with newline
*separators, then feed that to StringIO to create a file-like 
*object.  This
*object is (for most purposes) no different than the object returned by
*open(filename).  You should then be able to give this StringIO 
*object to the
*email package.
*
*Hope that this helps...
