# Specify the from address for the message.
adv_attr_accessor :from
# Specify the address (if different than the "from" address) to direct
# replies to this message.
adv_attr_accessor :reply_to
# Specify additional headers to be added to the message.

# Specify the order in which parts should be sorted, based on content-type.
# This defaults to the value for the +default_implicit_parts_order+.

adv_attr_accessor :mime_version
# The recipient addresses for the message, either as a string (for a single
# address) or an array (for multiple addresses).
adv_attr_accessor :recipients
# The date on which the message was sent. If not set (the default), the
# header will be set by the delivery agent.
adv_attr_accessor :sent_on
# Specify the subject of the message.
adv_attr_accessor :subject
# Specify the template name to use for current message. This is the "base"
# template name, without the extension or directory, and may be used to
# have multiple mailer methods share the same template.
adv_attr_accessor :template
# Override the mailer name, which defaults to an inflected version of the
# mailer's class name. If you want to use a template in a non-standard
# location, you can use this to specify that location.
adv_attr_accessor :mailer_name
# Define the body of the message. This is either a Hash (in which case it
# specifies the variables to pass to the template when it is rendered),
# or a string, in which case it specifies the actual text of the message.
adv_attr_accessor :body
# Alias controller_path to mailer_name so render :partial in views work.
