POP3 and IMAP settings

POP3

POP3 (Post Office Protocol) is an Internet protocol that makes it possible to retrieve e-mails from a mail server. If there is a connection to the Internet, e-mails are retrieved, stored on the local workstation and usually deleted from the mail server. This is the typical process. In the meantime, most e-mail providers offer the option of leaving e-mails on the mail server.

IMAP

IMAP (Internet Message Access Protocol) is an Internet protocol that allows access to and management of e-mails. In contrast to POP3, the e-mails remain on the mail server using IMAP. This ensures that the current status, including the folder structure, is always displayed even when several e-mail service applications (clients) are used. Local storage of data is therefore superfluous and increases security against potentially dangerous e-mails, as they can be deleted directly on the mail server. When setting up a local e-mail client, such as Outlook or Thunderbird, we recommend setting up IMAP.

SMTP

SMTP (Simple Mail Transfer Protocol) is an Internet protocol and is used in particular for sending or forwarding e-mails.
