In Asterisk 10, you can use the MessageSend application:

https://wiki.asterisk.org/wiki/display/AST/Asterisk+10+Application_MessageSend

In Asterisk 11, you'll also be able to use AMI:

https://wiki.asterisk.org/wiki/display/AST/Asterisk+11+ManagerAction_MessageSend

You may also want to look at the functions that modify the message fields:

https://wiki.asterisk.org/wiki/display/AST/Asterisk+10+Function_MESSAGE
https://wiki.asterisk.org/wiki/display/AST/Asterisk+10+Function_MESSAGE_DATA

You stated that you need to add some custom headers, which you can do with the
MESSAGE_DATA function.  In order to activate the forwarding, you could
do something like this:

exten => send_msg,1,NoOp()
same => n,Set(MESSAGE_DATA(X-Movial-Content)=application/x-movial-control;forwarding=true)
; If something needs to go in the body, replace this.  Otherwise,
; you can just remove it
same => n,Set(MESSAGE(body)=hello world!)
same => n,MessageSend(sip:to_address)

(Note: this wasn't tested, but hopefully it will give you an idea)
