This method injects an instance variable unconverted_fields into row and an accessor method for row called unconverted_fields(). The variable is set to the contents of fields.

Set the default value for the :load_limit option.

See new(). The initial default value is 25 MB.

Returns the inverse of the eigenvector matrix V

Nonsymmetric reduction to Hessenberg form.

Adds a response handler. For example, to detect when the server sends a new EXISTS response (which normally indicates new messages being added to the mailbox), add the following handler after selecting the mailbox:

imap.add_response_handler { |resp|
  if resp.kind_of?(Net::IMAP::UntaggedResponse) and resp.name == "EXISTS"
    puts "Mailbox now has #{resp.data} messages"
  end
}

Removes the response handler.

Opens a message writer stream and gives it to the block. The stream is valid only in the block, and has these methods:

puts(str = ”)

outputs STR and CR LF.

print(str)

outputs STR.

printf(fmt, *args)

outputs sprintf(fmt,*args).

write(str)

outputs STR and returns the length of written bytes.

<<(str)

outputs STR and returns self.

If a single CR (“r”) or LF (“n”) is found in the message, it is converted to the CR LF pair. You cannot send a binary message with this method.

Parameters

from_addr is a String representing the source mail address.

to_addr is a String or Strings or Array of Strings, representing the destination mail address or addresses.

Example

Net::SMTP.start('smtp.example.com', 25) do |smtp|
  smtp.open_message_stream('from@example.com', ['dest@example.com']) do |f|
    f.puts 'From: from@example.com'
    f.puts 'To: dest@example.com'
    f.puts 'Subject: test message'
    f.puts
    f.puts 'This is a test message.'
  end
end
