    I don't know much much people can help with the provided log file; but it contains only limited information. What it states is the emails sent to "anas78789@gmail.com" were deferred due to gmail rate-limiting. If all the emails are destined to single email account, it will be easy for you to track? perhaps a buggy script or cron.
