Revert "Merge pull request #146" (#307)

- This reverts commit d181cf6,
  reversing changes made to
  5d6dea3.
- PR #146 was erroneously merged into master.
- I don't want this feature (Allow multi email input for
  Service Group EMAIL) in 5.7.6 as it is not part of that
  release branch so has not been tested in preproduction.
- PR #247 ensures the feature is in the dev branch. The feature is
  already part of the release-5.8.0 branch.
