What is the use of this process dovenull (Dovecot's unauthorized user) ? Are these processes for real users? I only have 4 users but i constantly see a few processes under : dovenull (Dovecot's unauthorized user)
Can you give a few quick steps on how to secure Postfix and dovecot from hacking attempts or unauthorized users please?
