mail aliased --> gone?

[w trillich <will@serensoft.com>]

in /etc/aliases i've got
	postmaster: root
	root: will

and i used to get mail tagged for root, forwarded
to my 'will' mailbox.

since using mutt (i think that's the changeover point)
i've not been getting any root email.

i try 
	% mail root
	Subject: whatever
	where y'at?
	Cc:
	%
and it disappears.

my .muttrc contains only <<EOF
ignore "from " received content- mime-version status x-status message-id
ignore sender references return-path lines
macro index \eb '/~b ' 'search in message bodies'
set use_domain
unset write_bcc
set abort_nosubject=ask-yes
set alias_file="~/.muttrc"
unset askbcc
unset askcc
set folder="~/Mail"
lists debian-user
set sort=threads
set sort_aux=reverse-date-received
EOF

i'm on frozen(potato) with exim and mutt. 

where should i look?
