fix(notification): incorrect date header format (#3684)
* fix(notification): incorrect date header format

The date header in the email envelopes was incorrectly formatted missing a space between the `Date:` header and the value of this header. This also refactors the notification templates system allowing people to manually override the envelope itself.

Authelia uses templates to generate the HTML and plaintext emails sent via the notification service. Each template has two extensions; .html for HTML templates, and .txt for plaintext templates.

This guide effectively documents the usage of the template_path notification configuration option.

Template Names

Template Description
IdentityVerification Used to render notifications sent when registering devices or resetting passwords
PasswordReset Used to render notifications sent when password has successfully been reset

For example, to modify the IdentityVerification HTML template, if your template_path was configured as /config/email_templates, you would create the /config/email_templates/IdentityVerification.html file to override the HTML IdentityVerification template.

Placeholder Variables

In template files, you can use the following placeholders which are automatically injected into the templates:

Placeholder Templates Description
{{ .LinkURL }} IdentityVerification The URL associated with the notification if applicable.
{{ .LinkText }} IdentityVerification The display value for the URL associated with the notification if applicable.
{{ .Title }} All A predefined title for the email.
It will be "Reset your password" or "Password changed successfully", depending on the current step.
{{ .DisplayName }} All The name of the user, i.e. John Doe
{{ .RemoteIP }} All The remote IP address (client) that initiated the request or event.

Examples

This is a basic example:

<body>
  <h1>{{ .Title }}</h1>
  Hi {{ .DisplayName }}<br/>
  This email has been sent to you in order to validate your identity.
  Click <a href="{{ .LinkURL }}">here</a> to change your password.
</body>

Some Additional examples for specific purposes can be found in the examples directory on GitHub.

Envelope Template

There is also a special envelope template. This is the email envelope which contains the content of the other templates when sent via the SMTP notifier. It's strongly recommended that you do not modify this template unless you know what you're doing. If you really want to modify it the name of the file must be Envelope.tmpl.

This template contains the following placeholders:

In template files, you can use the following placeholders which are automatically injected into the templates:

{{ .UUID }} A string representation of a UUID v4 generated specifically for this email.
{{ .Host }} The configured host.
{{ .ServerName }} The configured TLS server_name.
{{ .SenderDomain }} The domain portion of the configured sender.
{{ .Identifier }} The configured identifier.
