Fixed #35514 -- Implemented dictionary-based MAILERS.

2026-05-13T21:00:56Z

See DEP 0018. Added: * MAILERS setting. * django.core.mail.mailers dict-like EmailBackend factory. * `using` argument to mail sending APIs. * `sent_using` attribute to mail.outbox messages in locmem backend. * MAILERS in startproject settings template, set to console backend. * AdminLogHandler.using argument. * BrokenLinkEmailsMiddleware.send_mail() method. Updated: * BaseEmailBackend to track the MAILERS alias used to construct it, and to report errors for unknown kwargs (OPTIONS). * EmailBackend implementations to initialize from kwargs (OPTIONS) only when MAILERS is being used. * smtp.EmailBackend to require `host` option and to default `port` option based on SSL/TLS options. * SimpleTestCase setup to substitute the locmem backend for all defined MAILERS configurations. * Django's tests that send mail to define MAILERS. Deprecated: * EMAIL_BACKEND and other backend-related EMAIL_* settings. * mail.get_connection(). * The `connection`, `fail_silently`, `auth_user`, and `auth_password` arguments to mail functions. * The EmailMessage.connection attribute. * BaseEmailBackend support for `fail_silently`. Backends that support fail_silently (SMTP, console, file) now implement it directly. * AdminEmailHandler.email_backend argument. Removed undocumented features without deprecation: * EmailMessage.get_connection() method. (send() now raises an error if a subclass has attempted to override it.) * EmailMessage.send() no longer sets self.connection to the connection used for sending. (It still _uses_ a pre-existing self.connection.) * AdminEmailHandler.connection() method. (Init now raises an error if a subclass has attempted to override it.) Thanks to Natalia Bidart for shepherding DEP 0018 and for extensive reviews and suggestions on the implementation. Thanks to Jacob Rief for the initial implementation and multiple iterations while refining the design. Co-authored-by: Jacob Rief

2026-05-07T01:39:16Z

Simplified and removed use of soon-to-be-deprecated or removed features from tests for AdminEmailHandler and BrokenLinkEmailsMiddleware. Added or updated cases to ensure `fail_silently` usage remains consistent during the transition to email providers. Changed custom FailingEmailBackend to respect fail_silently and record its use in a class-level property. In AdminEmailHandlerTest: * Added make_log_record() helper to reduce duplicated code. * Changed test_fail_silently() to send through the FailingEmailBackend, which will fail if not initialized with fail_silently=True. (Rather than inspecting attributes of a soon-to-be-deprecated connection.) * Simplified test_uses_custom_email_backend() by replacing monkeypatches with inspectable custom backend. * In test_customize_send_mail_method(), removed use of the undocumented self.connection() method and the soon-to-be-deprecated `connection` arg to mail_managers(). This test verifies a subclass can customize sending by mailing the managers rather than the admins. Involving a email backend connection was irrelevant. In BrokenLinkEmailsMiddlewareTest, added a case with FailingEmailBackend to verify send uses fail_silently=True.

Fixed #35581 -- Updated django.core.mail to Python's modern email API.

2025-07-25T11:50:02Z

- Changed EmailMessage.message() to construct a "modern email API" email.message.EmailMessage and added policy keyword arg. - Added support for modern MIMEPart objects in EmailMessage.attach() (and EmailMessage constructor, EmailMessage.attachments list). - Updated SMTP EmailBackend to use modern email.policy.SMTP. Deprecated: - Attaching MIMEBase objects (replace with MIMEPart) - BadHeaderError (modern email uses ValueError) - SafeMIMEText, SafeMIMEMultipart (unnecessary for modern email) - django.core.mail.forbid_multi_line_headers() (undocumented, but exposed via `__all__` and in wide use) - django.core.mail.message.sanitize_address() (undocumented, but in wide use) Removed without deprecation (all undocumented): - EmailMessage.mixed_subtype - EmailMultiAlternatives.alternative_subtype - Support for setting (undocumented) EmailMessage.encoding property to a legacy email.charset.Charset object Related changes: - Dropped tests for incorrect RFC 2047 encoding of non-ASCII email address localparts. This is specifically prohibited by RFC 2047, and not supported by any known MTA or email client. (Python still mis-applies encoded-word to non-ASCII localparts, but it is a bug that may be fixed in the future.) - Added tests that try to discourage using Python's legacy email APIs in future updates to django.core.mail.

Rewrapped long docstrings and block comments to 79 characters + newline using script from https://github.com/medmunds/autofix-w505.

Fixed #36163 -- Deprecated most positional arguments in django.core.mail.

2025-07-17T17:01:16Z

In public mail APIs, changed less frequently used parameters from keyword-or-positional to keyword-only, emitting a warning during the required deprecation period.
