+TF/02 There have been two changes concerned with submission mode:

  -      (a) A new option, /name=value, makes it possible to supply a user name
  -          to be inserted into any created Sender: header line. Typically, this
  -          would be looked up from $authenticated_id.
  +      Until now submission mode always left the return path alone, whereas
  +      locally-submitted messages from untrusted users have the return path
  +      fixed to the user's email address. Submission mode now fixes the return
  +      path to the same address as is used to create the Sender: header. If
  +      /sender_retain is specified then both the Sender: header and the return
  +      path are left alone.


  -      (b) The envelope sender address is forced to be the same as the
  -          submission mode sender address.
  +      Note that the changes caused by submission mode take effect after the
  +      predata ACL. This means that any sender checks performed before the
  +      fix-ups will use the untrusted sender address specified by the user, not
  +      the trusted sender address specified by submission mode. Although this
  +      might be slightly unexpected, it does mean that you can configure ACL
  +      checks to spot that a user is trying to spoof another's address, for
  +      example.


  -TF/02 The control = fakereject ACL modifier now has a fakedefer counterpart,
  +      There is also a new /name= option for submission mode which allows you
  +      to specify the user's full name to be included in the Sender: header.
  +      For example:
  +
  +        accept authenticated = *
  +               control = submission/name=${lookup {$authenticated_id} \
  +                                           lsearch {/etc/exim/namelist} }
  +
  +      The namelist file contains entries like
  +
  +        fanf: Tony Finch
  +
  +      And the resulting Sender: header looks like
  +
  +        Sender: Tony Finch <fanf@???>
  +
  +TF/03 The control = fakereject ACL modifier now has a fakedefer counterpart,
         which works in exactly the same way except it causes a fake SMTP 450
         response after the message data instead of a fake SMTP 550 response.
         You must take care when using fakedefer because it will cause messages
