deliveries

  $self->delivery_failure($email, $envelope);

  $self->recipient_failure($to);

If they return true, the sending will fail. If the transport was created with a true "allow_partial_success" attribute, recipient failures can cause partial success to be returned.

For more flexible failure modes, you can override more aggressively or can use Email::Sender::Transport::Failable.

This attribute stores an arrayref of all the deliveries made via the transport.

Each delivery is a hashref, in the following format:

  {
    email     => $email,
    envelope  => $envelope,
    successes => \@ok_rcpts,
    failures  => \@failures,
  }

Both successful and failed deliveries are stored.

A number of methods related to this attribute are provided:

• delivery_count
• clear_deliveries
• shift_deliveries
