User who sends more email
Recently I began to see a peak in the statistics on the amount of mail that is sent, around 200000 messages when the normal is 50~100 per hour, especially in unusual times such as 2:00 a.m., then checked the queue but I couldn't find anything strange.
I want to know how to find the email account who is sending more mail to prevent further happening in the future.
Or another strategy to avoid this happen again.
Thank you all.
