Question

Now that you have satisfactorily implemented IP addressing changes on the museum%u2019s network, the director asks you to help choose new mail server and client software that will be used by all employees. Because some
museum employees travel frequently, the mail system must allow them to keep messages on the mail server indefinitely. What protocols would your recommended mail system support or require? On the network diagram you drew in Case Project 10-1, add a mail server
at the location you think best. On this mail server, what ports must be available to clients in order for them to pick up their mail, given the protocol (or protocols) used by the mail system? (If you have forgotten significant port assignments, you can find
them in Table 4-3.)

Explanation / Answer

The POP3 port for inbound emails is 110 (995 if you want to use secured POP3) And the IMAP port for inbound emails is 143 (993 if you want to use secured IMAP) The SMTP port for outbound emails is 25 or 2525 (465 if you want to use secured SMTP)
