I only want to send email from my VPS through exim4.
When I run netstat -anltp | grep "LISTEN" the output is:
tcp 0 0 123.45.789.10:25 0.0.0.0:* LISTEN -
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN -
Does the fact that my public ip is listening on port 25 means that someone is sending mail also through my server?
My /var/log/exim4/mainlog file is filled with message like below and I got a message from google saying "mail sent from your IP address has been blocked".
