_Requires Symcon >= 2.2_

The POP3 module can be configured using the configuration page within the [Object Tree](../components/management-console.md) of the [Management Console](../components/management-console.md). The parameters for host and port can be taken from the manual of the mail provider. The username and password are the login data for the e-mail account.

To display the e-mails in the visualization, the interval must be set. It determines the cyclic request of the inbox. Only the subject line is requested. The complete e-mail will only be loaded when requested by the visualization.

On the variable "Last Message" can be determined if and when new mails arrive. If no e-mails are in the mailbox, the variable has the value 0. Unlike IMAP, the display of the number of unread variables is technically not possible for POP3.
