install

composer req belsignum/disposable-email

Tests

Run tests from extension directory:

vendor/bin/phpunit -c Build/phpunit/UnitTests.xml
vendor/bin/phpunit -c Build/phpunit/FunctionalTests.xml

Alternatively via composer scripts:

composer test:unit
composer test:functional

The CI workflow runs both test suites (Unit and Functional).

Extension configuration options

basic.type - Lists to use

• Disable validation
• Disposable email provider
• Free email provider
• Disposable & free email provider
• Custom lists only

basic.customLists - Custom Lists (comma separated list of public URIs) Only absolute https:// URLs are supported.

powermail.overloadEmailValidation - Overload Email Validation, else adds additional validation rule

Powermail validation rule

• Disposable Email
• Or overload Email validation rule - Set extension configuration powermail.overloadEmailValidation=1

Powermail list type override via TypoScript

Use TypoScript to override the list type for Powermail validation.

plugin.tx_powermail.settings.setup.tx_disposableemail.overrideExtensionSettings {
  # one override for current Powermail context
  type = disposable

  # optional form specific mapping
  typeByForm {
    # disable disposable email validation for this form
    100 = disable

    123 = disposable
    456 = freemail
  }
}

typeByForm has priority over type. In typeByForm, use the UID of the default language form record. Localized forms are resolved via l10n_parent. Supported values are disable, disposable, freemail, both, customListsOnly.

CMS-Form

• Validator for E-Mail Field comparing E-Mail Address against lists of disposable and free mail providers
• Validator for E-Mail Field comparing username or email address in fe_users
• Optional validator option listType (disable|disposable|freemail|both|customListsOnly) to override extension configuration per field

List storage and deduplication

• Domains are stored with provider_type (disposable, freemail, custom).
• Deduplication is done per provider_type.
• Custom lists are stored as custom and are checked in addition to selected built-in list types.
• DB-level uniqueness is enforced by uniq_domain_provider_type (domain, provider_type).
