# Adds 'delay' and 'delay_for' to ActionMailer to offload arbitrary email
# delivery to Sidekiq. Example:
#
# UserMailer.delay.send_welcome_email(new_user)
# UserMailer.delay_for(5.days).send_welcome_email(new_user)
# UserMailer.delay_until(5.days.from_now).send_welcome_email(new_user)

# I think it's reasonable to assume that emails should take less
# than 30 seconds to send.

(target, method_name, args) = YAML.load(yml)
msg = target.send(method_name, *args)
# The email method can return nil, which causes ActionMailer to return
# an undeliverable empty message.
