DESCRIPTION

Mojolicious::Plugin::EmailMailer is a Mojolicious plugin to send mail through Email::Mailer.

Inspired by Mojolicious::Plugin::Mail, I needed to be able to send mail through a server which uses starttls.

CONFIGURATION

All parameters are optional.

Except for how and howargs, the configuration parameters are parameters for Email::Mailer’s new method. See https://metacpan.org/pod/Email::Mailer#PARAMETERS for available parameters. Those parameters will be the default ones and can be overwritten when using send_mail and send_multiple_mail helpers (see below).

As for how and howargs parameters, they are used to choose the transport for the mails (sendmail, a SMTP server…). The how parameter can be:

DevNull - happily throw away your mail
Failable - a wrapper to makes things fail predictably
Maildir - deliver mail to a maildir on disk
Mbox - deliver mail to an mbox on disk
SMTP - send email over SMTP
SMTP::Persistent - an SMTP client that stays online
Sendmail - send mail via sendmail(1)
Test - deliver mail in memory for testing
Wrapper - a mailer to wrap a mailer for mailing mail

Note that the how parameter is case-insensitive.

When giving a how parameter, the transport will be an instance of Email::Sender::Transport::$how, constructed with howargs as parameters.

See https://metacpan.org/release/Email-Sender to find the available parameters for the transport you want to use.

HELPERS

Mojolicious::Plugin::EmailMailer contains three helpers: send_mail, send_multiple_mail and render_mail.

send_mail

Straightly send a mail, according to the given arguments and plugin configuration.

  $self->send_mail(
      to         => 'test@example.org',
      from       => 'test@example.org',
      'reply-to' => 'reply_to+test@example.org',
      cc         => '..',
      bcc        => '..',
      subject    => 'Test',
      text       => 'use Perl or die;',
      html       => '</p>use Perl or die;</p>',
  );

See https://metacpan.org/pod/Email::Mailer#PARAMETERS for available parameters.

If send_mail() succeeds, it'll return an instantiated Email::Mailer object based on the combined parameters. If it fails, it will return 0 and create a log error message;

All parameters, will be used as mail headers, except the following ones:

html
text
embed
attachments
process
data
transport
width

Note that the Subject, to and From headers will be automatically UTF-8 encoded by the plugin, then encoded as mimewords by Email::Mailer.

When sending a text-only mail (with or without attachments), the default values of Content-Transfer-Encoding and Content-Type headers are respectively quoted-printable and text/plain; charset=utf8 and the text is encoded according to the charset specified in the Content-Type header;

send_multiple_mail

Email::Mailer allows to prepare a mail and send it more than one time, with different overriden parameters:

  Email::Mailer->new(
      from    => $from,
      subject => $subject,
      html    => $html
  )->send(
      { to => 'person_0@example.com' },
      { to => 'person_1@example.com' },
      {
          to      => 'person_2@example.com',
          subject => 'Override $subject with this',
      }
  );

You can do the same with send_multiple_mail:

  $self->send_multiple_mail(
      mail => {
          from    => $from,
          subject => $subject,
          html    => $html
      },
      send => [
          { to => 'person_0@example.com' },
          { to => 'person_1@example.com' },
          {
              to      => 'person_2@example.com',
              subject => 'Override $subject with this',
          }
      ]
  );

mail, a hashref, obviously contains the Email::Mailer-new()> arguments and send, an arrayref, contains the Email::Mailer-send()> arguments.

If send_multiple_mail() succeeds, it'll return an array or arrayref (based on context) of the Email::Mailer objects ultimately created. If it fails, it will return 0 and create a log error message;

Note that the subject will be UTF-8 encoded, then encoded as mimeword, like this:

  use MIME::Words qw(encode_mimeword);
  $subject = encode_mimeword(encode('UTF-8', $subject), 'q', 'UTF-8');

When sending a text-only mail (with or without attachments), the default values of Content-Transfer-Encoding and Content-Type headers are respectively quoted-printable and text/plain; charset=utf8 and the text is encoded according to the charset specified in the Content-Type header;

render_mail

  my $data = $self->render_mail('user/signup');

  # or use stash params
  my $data = $self->render_mail(template => 'user/signup', user => $user);

Render mail template and return data, mail template format is mail, i.e. user/signup.mail.ep.

EXAMPLES

  my ($to, $from, $subject, $text, $html);

  # send a simple text email
  $self->send_mail(
      to      => $to,
      from    => $from,
      subject => $subject,
      text    => $text
  );

  # send multi-part HTML/text email with the text auto-generated from the HTML
  # and images and other resources embedded in the email
  $self->send_mail(
      to      => $to,
      from    => $from,
      subject => $subject,
      html    => $html
  );

  # send multi-part HTML/text email with the text auto-generated from the HTML
  # but skip embedding images and other resources
  $self->send_mail(
      to      => $to,
      from    => $from,
      subject => $subject,
      html    => $html,
      embed   => 0
  );

  # send multi-part HTML/text email but supply the text explicitly
  $self->send_mail(
      to      => $to,
      from    => $from,
      subject => $subject,
      html    => $html,
      text    => $text
  );

  # send multi-part HTML/text email with a couple of attached files
  use IO::All 'io';
  $self->send_mail(
      to          => $to,
      from        => $from,
      subject     => $subject,
      html        => $html,
      text        => $text,
      attachments => [
          {
              ctype  => 'application/pdf',
              source => 'file.pdf',
          },
          {
              ctype    => 'application/pdf',
              content  => io('file.pdf')->binary->all,
              encoding => 'base64',
              name     => 'file.pdf',
          },
      ],
  );

  # build an email and iterate over a data set for sending
  $self->send_multiple_mail(
      mail => {
          from    => $from,
          subject => $subject,
          html    => $html
      },
      send => [
          { to => 'person_0@example.com' },
          { to => 'person_1@example.com' },
          {
              to      => 'person_2@example.com',
              subject => 'Override $subject with this',
          }
      ]
  );

  # setup a second mail object based on the first but changing the "from"
  my $mail_0 = $self->send_mail(
      from    => $from,
      subject => $subject,
      html    => $html
  );
  if ($mail_0) {
      my $mail_1 = $mail_0->new(from => 'different_address@example.com');
      $mail_1->send;
  }
