How to not change logger for only one class--not log full mail text

Ruby on Rails

Has anybody found the logging of the payload of emails annoying during testing and development?

In the code below for ActionMailer, it logs the full payload of emails. I like to turn this off while debugging even though I’m setting the logger to debug level.

What’s the cleanest way to override this? Maybe monkey patch the logger method? If so, any example?

    module ActionMailer
      class LogSubscriber < ActiveSupport::LogSubscriber
        def deliver(event)
          return unless logger.info?
          recipients = Array(event.payload[:to]).join(', ')
          info("\nSent mail to #{recipients} (#{event.duration.round(1)}ms)")
          debug(event.payload[:mail])
        end
    
        def logger
          ActionMailer::Base.logger
        end
      end
    end
    
    ActionMailer::LogSubscriber.attach_to :action_mailer
