Description of Problem:
Here is my current mail setup :
I get my mail with fetchmail. procmail puts it
into 4 mbox files : One for my personnal mail, one
for my girlfriend mail, One for mailing list and
one for spam.
I have done so that the Gnome Inbox Monitor alert
me only when a personnal Mail arrives (i don't
want to be bothered by mailing list or spam).

In Evolution, I have set up 4 mail accounts (in
Local delivery mode), one for each mbox files.

The problem is that the 2 accounts created for the
spam and the mailing list mboxes show up into the
"From" combo box of composer window. This is not
great :-(

So it would be nice if :
 o I could mark a mail account as "Hidden".
Evolution use it as a mail source but it don't
show up as an identity in the "From" combo box.
 o Or I could specify several mboxes for one mail
account or specify a directory of mboxes in which
Evolution will fetch the mail.
