Have Herald e-mail or otherwise alert creator of a task or differential



I have several Herald rules enforcing things when creating new tasks or differentials.

For example;

  • check if a help desk ticket ID was mentioned when creating a task tagged with customer bug
  • make sure there is a release note when creating a diff that touches certain files

I was hoping for a way to alert the creator of these objects, at the moment Herald will just leave a comment. I couldn’t find a dynamic owner option or something for the send e-mail action. Another option could be a webhook and custom daemon somewhere but that seems a bit convoluted.

Is there any way to achieve this behaviour with just Phabricator?
