## Description

# 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 it's 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>, ada@test.lindsaar.net'
    mail.sender    #=> ['Mikel Lindsaar <mikel@test.lindsaar.net>', 'ada@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>, ada@test.lindsaar.net\r\n'
    mail[:sender].decoded   #=> 'Mikel Lindsaar <mikel@test.lindsaar.net>, ada@test.lindsaar.net'
    mail[:sender].addresses #=> ['mikel@test.lindsaar.net', 'ada@test.lindsaar.net']
    mail[:sender].formatted #=> ['Mikel Lindsaar <mikel@test.lindsaar.net>', 'ada@test.lindsaar.net']
