Hi, My server is sending large amounts of spam. If I check the mail log files they are sometimes 350mb because of alle mail that is send. This is what is in the logging: I'm unable to see who the user is that sends it. The mail logging just says that a mail is send to someone. I can't find out if it is the server or some client. Is there a way to see who sends these mails? What is the best logging to check for this? Thanks in advance for your help.
