Testing Email locally? Could i reroute email to watchdog?
Yes, you can use the Maillog / Mail Developer module.


  Maillog provides an easy possibility to log all Mails for debugging purposes. It's possible to prevent the mails to being sent, so there is no need for an extra mail server to test the mail functionality of other modules or the Drupal core. Additionally you can immediately display the mail through the devel dpm() facility.
