The email provides the configuration details, most importantly, the server name.
As you can see, there are two port numbers listed under the incoming server name. Those are for the email receiving protocols, IMAP, and POP3. Which you should use depends on how you access your email.
IMAP is the best choice if you check and send mail from multiple devices, or if more than one user accesses the same account. Reading, sending, replying, etc. all take place on the email server. Then those changes are synced with every device that connects to the account.
So, for example, if you delete an email on your phone then log in to webmail later, the message will be deleted there as well.
POP3 may be an option if you only check and send email from one device or location, need to read messages offline, or need to archive old messages. POP3 downloads the emails and saves them on your local computer or device. Reading, sending, replying, etc. all happen locally in your email application.
They are not synced with any other device that may connect to the account. Many email accounts have storage space limits. So if you need to archive old messages, POP3 may be the best method.
