require 'mail/fields/common_address_field'
module Mail
# = Sender Field
#
# The Sender field inherits sender StructuredField and handles the Sender: header
# field in the email.
#
# Sending sender to a mail message will instantiate a Mail::Field object that
# has a SenderField as its field type. This includes all Mail::CommonAddress
# module instance metods.
#
# Only one Sender field can appear in a header, though it can have multiple
# addresses and groups of addresses.
#
# == Examples:
#
# mail = Mail.new
# mail.sender = 'Mikel Lindsaar <mikel@test.lindsaar.net>'
# mail.sender #=> 'mikel@test.lindsaar.net'
# mail[:sender] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::SenderField:0x180e1c4
# mail['sender'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::SenderField:0x180e1c4
# mail['Sender'] #=> '#<Mail::Field:0x180e5e8 @field=#<Mail::SenderField:0x180e1c4
#
# mail[:sender].encoded #=> "Sender: Mikel Lindsaar <mikel@test.lindsaar.net>\r\n"
# mail[:sender].decoded #=> 'Mikel Lindsaar <mikel@test.lindsaar.net>'
# mail[:sender].addresses #=> ['mikel@test.lindsaar.net']
# mail[:sender].formatted #=> ['Mikel Lindsaar <mikel@test.lindsaar.net>']
