Some do not use namespaces and every library we encountered was merely a collection of scalar property bags than objects using encapsulation. Although we used these libs with joy in the past, they do not meet current quality standards. So, we built a new and better library according to modern programming principles. Use this if you want to send e-mails over different transports and protocols using immutable messages and streams. Send message quick and easy --------------------------- [](#send-message-quick-and-easy) ``` use Genkgo\Mail; $message = (new Mail\MessageBodyCollection('Hello World')) ->withAttachment(new Mail\Mime\FileAttachment('/order1.pdf', new Mail\Header\ContentType('application/pdf'))) ->createMessage() ->withHeader(new Mail\Header\Subject('Hello World')) ->withHeader(Mail\Header\From::fromEmailAddress('from@example.com')) ->withHeader(Mail\Header\To::fromSingleRecipient('to@example.com', 'name')) ->withHeader(Mail\Header\Cc::fromSingleRecipient('cc@example.com', 'name')); $transport = new Mail\Transport\SmtpTransport( Mail\Protocol\Smtp\ClientFactory::fromString('smtp://user:pass@host/')->newClient(), Mail\Transport\EnvelopeFactory::useExtractedHeader() ); $transport->send($message); ``` Install using composer ---------------------- [](#install-using-composer) ``` $ composer require genkgo/mail ``` Features -------- [](#features) - Use SMTP or mail() to send messages - Use IMAPv4 to read messages from your mailbox (no extension required) - Create replies and forward messages, including quoting of original message - Queue messages when transport fails - Automatically connects and reconnects after interval to SMTP server - Automatically generate alternative text for formatted messages - Optimal encoded headers, so no excessive (Q/B) encoded headers - Optimal encoded multipart messages - Only streams and connections are mutable - Messages and actors are immutable - Value objects protect against invalid states - Streams make sure the library has a low memory burden - Many objects but still easy API - 90%+ test coverage - Uses highest PHPStan detection level - Only uses TLS < 1.2 if not otherwise possible - Discourages SSL - DKIM signed message - Security is highly prioritized - SMTP server for testing purposes - Great RFC compliance - Cast messages to valid string source - Library has no external dependencies (but uses intl extension) - Only supports [PHP versions that are not EOL](https://www.php.net/supported-versions.php) Upcoming features ----------------- [](#upcoming-features) - Encrypted and signed messages Not planned ----------- [](#not-planned) The following features are not planned for development by the owners, but could become part of the library when initiative is taken by the community. - POP Support - Mailbox abstraction layer Documentation ------------- [](#documentation) - [English documentation](https://mail.readthedocs.io/) - [PHP7.1未満お断り！最新PHPメーラーライブラリ Genkgo/Mail を試してみる - Qiita](https://qiita.com/mpyw/items/88161f9a809e063823c6) RFC-compliance -------------- [](#rfc-compliance) This library tends to be as compliant with e-mail RFCs as possible.
