Module lettre::transport[−][src]

Sending Messages

This section explains how to manipulate emails you have created.

This mailer contains several different transports for your emails. To be sendable, the emails have to implement Email, which is the case for emails created with lettre::builder.

The following transports are available:

  • The SmtpTransport uses the SMTP protocol to send the message over the network. It is the preferred way of sending emails.
  • The SendmailTransport uses the sendmail command to send messages. It is an alternative to the SMTP transport.
  • The FileTransport creates a file containing the email content to be sent. It can be used for debugging or if you want to keep all sent emails.
  • The StubTransport is useful for debugging, and only prints the content of the email in the logs.
