README

A Template Mailer for Neos Flow or/and CMS Projects.

What does it do?

This package provides a service class intended to be used as base class for sending Fluid templates as mails. In addition it contains a debugging aspect for cutting off and/or redirecting all mails (sent by SymfonyMailer) in a development environment. Moreover, it supports using environment variables to build the DSN for the Symfony Mailer.

Releases und compatibility:

Using the service in your own plugins to use fluid templates for mails

Configure default from address:

FormatD:
  Mailer:
    defaultFrom:
      address: 'example@example.com'
      name: 'Example'

Extend AbstractMailerService and add methods as needed following the example of sendTestMail().

intersept all mails in a dev environment

Configure swiftmailer to intersept all mails send by your neos installation (not only by the service).

This is an example which intercepts all mails and redirects them to example@example.com and secondexample@example.com:

FormatD:
  Mailer:
    interceptAll:
      active: true
      recipients: ['example@example.com', 'secondexample@example.com']
    bccAll:
      active: false
      recipients: []

Handling Embedded Images

The method AbstractMailerService->setMailContentFromStandaloneView() has a parameter to embed all images into the mail body. This is handy if you have an installation that is protected by a .htaccess file for example, or the user may not have access to the internet when reading the email. GMail also cannot display images if they are included from a local domain.

FormatD.Mailer can be configured to replace all image urls by local paths (if you specify a baseUrl in your flow configuration). This is needed it the server cannot make a web-request to itself (also maybe due to a .htaccess or something).

FormatD:
  Mailer:
    localEmbed: true

Disable embed for specific images

You can disable image embedding for specific images by adding data-fdmailer-embed="disable" as data attribute to the image tag. This is useful for tracking pixels where you dont want the local embedding.

Using environment variables to build a SMTP transport DSN

Use the special DSN fd-mailer in the SymfonyMailer configuration. This transport will then use the configuration given under FormatD.Mailer.smtpTransport to build the actual DSN and actual SmtpTransport object. host is mandatory, all other parts are optional.

For special cases the automatic DSN construction can be omitted by passing the DSN directly at Neos.SymfonyMailer.mailer.dsn.

Neos:
  SymfonyMailer:
    mailer:
      dsn: 'fd-mailer'

FormatD:
  Mailer:
    smtpTransport:
      host: '%env:SMTP_HOST%'
      encryption: '%env:SMTP_ENCRYPTION%'
      port: '%env:SMTP_PORT%'
      username: '%env:SMTP_USERNAME%'
      password: '%env:SMTP_PASSWORD%'
       
      # Optional: Query params appended to the DSN, use with caution and only when necessary
      options:
        # Do not verify server TLS certificate
        verify_peer: 1
        # Do not try `STARTTLS` at all
        auto_tls: 'false'
        # Use `STARTTLS` even when not announced in server capabilities
        require_tls: 'true'
        

The encryption param is cast to boolean, with the 'false' string being interpreted falsy as well. If true, the scheme will be smtps, thus the Symfony SMTP transport tries to establish a TLS encrypted channel right away. If encryption is false, then the transport will still try to upgrade the connection via STARTTLS, when that is announced by the server!

The options config is completely optional and could be omitted to use SymfonyMailer's sane defaults. It can be used to define query parameters appended to the DSN, as described in the SymfonyMailer documentation.
