• Disallow calling #deliver_later 

  in the wake of making neighborhood adjustments to the message which would be lost when the conveyance job is enqueued.

  
  
  Prevents a common, hard-to-find bug like:

  message = Notifier.welcome(user, foo)
  message.message_id = my_generated_message_id
  message.deliver_later
  

  The message_id is silently lost! Only the mailer arguments are passed to the delivery job.
  This raises an exemption now. Make alterations to the message inside the mailer method  rather, or utilize a custom Active Job to manage delivery instead of utilizing
  
  #deliver_later.

• Removes -t from default Sendmail arguments to match the underlying Mail::Sendmail setting.
