- !ruby/struct:SM::Flow::P 
  body: If both of <tt>user</tt> and <tt>secret</tt> are given, SMTP authentication will be attempted using the AUTH command. <tt>authtype</tt> specifies the type of authentication to attempt; it must be one of :login, :plain, and :cram_md5. See the notes on SMTP Authentication in the overview.

  level: 3
  text: Block Usage

- !ruby/struct:SM::Flow::H 
  level: 3
  text: Example
- !ruby/struct:SM::Flow::P 
  body: This is very similar to the class method SMTP.start.
- !ruby/struct:SM::Flow::VERB 
  body: "    require 'net/smtp'\n    smtp = Net::SMTP.new('smtp.mail.server', 25)\n    smtp.start(helo_domain, account, password, authtype) do |smtp|\n      smtp.send_message msgstr, 'from@example.com', ['dest@example.com']\n    end\n"
- !ruby/struct:SM::Flow::P 
  body: The primary use of this method (as opposed to SMTP.start) is probably to set debugging (#set_debug_output) or ESMTP (#esmtp=), which must be done before the session is started.
- !ruby/struct:SM::Flow::H 
  level: 3
  text: Errors
- !ruby/struct:SM::Flow::P
