    To avoid filtering e-mail traffic, ports 25, 110, and 143 should be left open. Port 25 is used for SMTP (Simple Mail Transfer Protocol) to send e-mails, port 110 is used for POP3 (Post Office Protocol version 3) to receive e-mails, and port 143 is used for IMAP (Internet Message Access Protocol) to access e-mails on a mail server. By leaving these ports open, the necessary protocols for sending, receiving, and accessing e-mails can function properly without being filtered or blocked.
