https://{youraccountname}.api-us1.com/api/3/forms//allowPersonalEmailProviders
Makes the form take submissions from personal email providers, such as gmail.com, again, by setting options.block_personal_email_providers to false. Domains on options.blocked_email_domains stay blocked, gmail.com included if it is listed there. Allowing when they are already allowed changes nothing and succeeds. Use PUT /forms/{id}/blockPersonalEmailProviders to block them again. Requires the permission to edit forms.
