async-mailer

An async dyn Mailer trait with runtime-pluggable Outlook (Office365) and SMTP implementations.

Example:

``rust // Create aBox`. // // Alternative implementations can be used.

let mailer = OutlookMailer::new( "", "", "" ).await?;

// Alternative: let mailer = SmtpMailer::new( "smtp.example.com", 465, SmtpInvalidCertsPolicy::Deny, "", "" );

// Further alternative mailers can be implemented by third parties.

// The trait object is Send and Sync and may be stored e.g. as part of your server state.

// Build a message using the re-exported mail_builder::MessageBuilder'. // For blazingly fast rendering of beautiful HTML mail, I recommend combiningaskamawithmrml`. let message = MessageBuilder::new() .from(("From Name", "from@example.com")) .to("to@example.com") .subject("Subject") .text_body("Mail body");

// Send the message using the implementation-agnostic dyn Mailer. mailer.send_mail(&message).await?; ```

Roadmap

DKIM support is planned to be implemented on the SmtpMailer.

Further mailer implementations are possible. Please open an issue and ideally provide a pull request to add your alternative mailer implementation!
