Transport Types

A Transport is the component which actually does the sending. You need to provide a Transport object to the Mailer class and there are several possible options.

Typically you will not need to know how a Transport works under-the-surface, you will only need to know how to create an instance of one, and which one to use for your environment.

  1. The SMTP Transport
    The SMTP Transport sends messages over the (standardized) Simple Message Transfer Protocol. It can deal with encryption and authentication.
  2. The Sendmail Transport
    The Sendmail Transport sends messages by communicating with a locally installed MTA – such as sendmail.
  3. The Mail Transport
    The Mail Transport sends messages by delegating to PHP's internal mail() function.
