You need in Muttrc or ~/.muttrc :
set envelope_from=yes
#
# Name: envelope_from
# Type: boolean
# Default: no
#
#
# When set, mutt will try to derive the message's envelope
# sender from the "From:" header. Note that this information is passed
# to sendmail command using the "-f" command line switch, so don't set this
# option if you are using that switch in $sendmail yourself,
# or if the sendmail on your machine doesn't support that command
# line switch.
