Bundle error emails are going to all administrators

When a bundle is installed, the default email recipients for bundle messages is ''All Bundle Admins".  This setting can be changed, even for managed or locked bundles:

1. Navigate to  Customization > SuiteBundler > Search and Install Bundle > List
2. Click the "Name" field of the bundle you wish to change
3. Click the "Messages" subtab of the bundle record
4. Click and change the Email Recipients dropdown to the desired setting:

All Bundle Admins - All administrators and users with the SuiteBundler permission in your account receive bundle messages as email
None - Bundle messages should not be send as email to anyone in your account
Custom - Bundle messages should be sent as email only to selected bundle administrators (click the Edit List link to select them)
