It does.
>From the Exim 4.1x specification:
-f <address>
This option sets the address of the envelope sender of a
locally-generated message (also known as the return path). The option
can normally be used only by a trusted user, but untrusted_set_sender
can be set to allow untrusted users to use it. In the absence of -f, or
if the caller is not allowed to use it, the sender of a local message is
set to the caller's login name at the default qualify domain.
The use of -f is not restricted when testing a filter file with -bf or
when testing or verifying addresses using the -bt or -bv options. There
is also no restriction of the use of the special setting -f <> to send a
message with an empty sender; such a message can never provoke a bounce.
Allowing untrusted users to change the sender address does not of itself
make it possible to send anonymous mail. Exim still checks that the
From: header refers to the local user, and if it does not, it adds a
Sender: header, though this can be overridden by setting
no_local_from_check.
White space between -f and the <address> is optional (that is, they can
be given as two arguments or one combined argument). The sender of a
locally-generated message can also be set (when permitted) by an initial
``From '' line in the message - see the description of -bm above - but
if -f is also present, it overrides ``From ''.
