The main page gives you a list of delivered messages. The letter U can be found next to those which have not been read yet (the letter stands for “unread”).
If you want to read a message, click on its subject. As regards attachments, these are opened and displayed automatically provided it is convenient to do so. The others can either be opened by being clicked on or downloaded to your computer. The application also allows you to edit the old and create new mail folders. For this purpose, please use the following path:

If you select more than one message (by using the checkboxes placed next to these), the operation you perform will be carried out for all the messages selected. Thus you can read, delete, download, and move all these with a single click. The individual messages can be marked with a star (as those of high importance), a certain tag or color. Using the option titled Tags administration, you can create your own tags or rename the old ones. The order in which messages are displayed can be changed by clicking on the title of the column containing the information by which you want the messages to be sorted.

Clicking on the sender's name in the message list displays a menu with fast options.
