Overview

Mail::Address handles all email addresses in Mail. It takes an email address string and parses it, breaking it down into its component parts and allowing you to get the address, comments, display name, name, local part, domain part and fully formatted address.

Mail::Address requires a correctly formatted email address per RFC2822 or RFC822. It handles all obsolete versions including obsolete domain routing on the local part.

a = Address.new('Mikel Lindsaar (My email address) <mikel@test.lindsaar.net>')
a.format       #=> 'Mikel Lindsaar <mikel@test.lindsaar.net> (My email address)'
a.address      #=> 'mikel@test.lindsaar.net'
a.display_name #=> 'Mikel Lindsaar'
a.local        #=> 'mikel'
a.domain       #=> 'test.lindsaar.net'
a.comments     #=> ['My email address']
a.to_s         #=> 'Mikel Lindsaar <mikel@test.lindsaar.net> (My email address)'

#address(output_type = :decode) ⇒ Object

Returns the address that is in the address itself. That is, the local@domain string, without any angle brackets or the like.

a = Address.new('Mikel Lindsaar (My email address) <mikel@test.lindsaar.net>')
a.address #=> 'mikel@test.lindsaar.net'

  else
    local(output_type)
  end
end

#address=(value) ⇒ Object

Provides a way to assign an address to an already made Mail::Address object.

a = Address.new
a.address = 'Mikel Lindsaar (My email address) <mikel@test.lindsaar.net>'
a.address #=> 'mikel@test.lindsaar.net'

#commentsObject

Returns an array of comments that are in the email, or nil if there are no comments

a = Address.new('Mikel Lindsaar (My email address) <mikel@test.lindsaar.net>')
a.comments #=> ['My email address']

b = Address.new('Mikel Lindsaar <mikel@test.lindsaar.net>')

#display_name=(str) ⇒ Object

Provides a way to assign a display name to an already made Mail::Address object.

a = Address.new
a.address = 'mikel@test.lindsaar.net'
a.display_name = 'Mikel Lindsaar'
a.format #=> 'Mikel Lindsaar <mikel@test.lindsaar.net>'

Returns the domain part (the right hand side of the @ sign in the email address) of the address

#format(output_type = :decode) ⇒ Object

Returns a correctly formatted address for the email going out. If given an incorrectly formatted address as input, Mail::Address will do its best to format it correctly. This includes quoting display names as needed and putting the address in angle brackets etc.

a = Address.new('Mikel Lindsaar (My email address) <mikel@test.lindsaar.net>')
a.format #=> 'Mikel Lindsaar <mikel@test.lindsaar.net> (My email address)'
