[evolution-patches] [IMAP][Mailer] Headers Fetching

["P Sankar" <psankar novell com>]

Hi,

As per a discussion with Fejj, I came to know that Evo will work faster
for IMAP accounts if we get only a minimalistic subset of HEADER fields
instead of getting full HEADERS. The attached patch does that.  Things
seem to be working faster because of this. This could be further
improved if we find out someway of restricting the mailing-list headers
too.
