When you run a command like netstat -n on a Windows or Linux computer, you will see a list of the local addresses (and ports) and the foreign addresses (and ports) that are connected to them.

    What Are The Common Ports?

  • There are 110 POP3s per hour.
  • The POP3 SSL certificate is 995.
  • IMAP – 143.
  • The IMAP SSL protocol is 993.
  • What Are Ports 110 And 443 Used For?

    POP3 is only used for incoming emails, not outgoing emails, and TCP port 110 is used for POP3. HTTPS is the protocol used by TCP port 443, not email.
