One way to get what you want is to use esmtp:

# muttrc
set sendmail="/usr/bin/esmtp"

# esmtprc
identity = user at ho.st
  hostname = smtp.ho.st:587
  username = user at ho.st
  password = password
  starttls = enabled
  message_id = disabled

# man esmtprc
message_id

  Whether to set the Message-ID field of the message before sending.
  Normally the receiving MTA sets the Message-ID if missing, so you can
  turn this off if your sending host does not have a fully qualified
  domain name.

  Allowed values are either enabled or disabled. It defaults to enabled.
