Does anyone know of a good way to get emails generated by MR scripts to actually send in sandbox? Currently our environment is set to send emails to the current logged in user, which in this case would be the system executing the script,

For Sandbox, unless there is something new I'm not aware of, you need to set the email addresses that you want:

Yeah that's currently what I have to do. I was hoping there was a runtime flag I could set during execution so I don't have to get a sign off each time I forward all mail to my account. (Users still need to receive emails as part of their UATs, so I can't just permanently setup a mailbox). I wish NS would give us something like mailhog where we can see a rendered example instead of a stripped view from the mail log.
