[Exim] Off topic: MUTT?

I apologize for going off topic here, but this is the "friendliest"
mail-related list i have been on :)

Can someone give me a pointer to howto set MUTT up as either a "IMAP only"
or "Maildir/IMAP" mua? I am confused by the documentation, and figured that
"someone has got to have done that before me".
