  2. Look for settings or options related to outgoing mail (SMTP) and incoming mail (POP3 or IMAP).
  3. Check the server names and ports listed for these settings. These are likely to be the incoming and outgoing mail firewall servers.

Method 2: Check your network settings or router configuration
