Explanations: What should have been port 143 was probably configured incorrectly if the person can send but not receive e-mail. The Internet Message Access Protocol (IMAP) receives e-mail and uses port 143. The Simple Mail Transfer Protocol (SMTP) uses port 25 by default to send mail but will use port 443 if SSL or TLS security is implemented. Port 110 is the POP3 e-mail port. POP3 also is used to receive e-mail, but not in this question’s scenario. By the way, another port that is used for SMTP is 587. This is done to avoid being blocked by ISPs and to reduce spam. Mobile devices such as Android phones can be a little more difficult to configure e-mail on, as compared to PCs. Be sure to work with mobile devices and go through the steps of setting up e-mail on both Android and iOS.
