How to set the menu settings of a newly created page in mailhandler module?

I would like to modify the mailhandler module so that the Parent item can be set as part of the commands supported by mailhandler. This is so that when a user submits a new post via email, they can have it automatically show up as a link under a particular menu in the site. I've read through the menu module and the mailhandler module but could use some suggestions or examples on how to do this. Thanks!
