Follow a step-by-step procedure to access mailbox functionality, choose box type, input necessary information, save configurations, and link e docTags: createdAt: 2021-10-27T01:01:51.000Z --- This functionality is designed to **configure the sending and receiving of e-mails from different servers** in order to meet different contracts, so a **CITSmart** can serve different clients and each one will have its own mailbox. In this case, you can use a send/read e-mail account (e.g.: [email@company.com](mailto\:email@company.com)) on an XPTO company contract, and another e-mail account belonging to a different business agreement (e.g.: [email@company2.com](mailto\:email@company2.com)). ## Procedure 1. Access the functionality through the main menu `Parametrization > Mailbox`; 2. Click on "**New**"; 3. Choose the type of box. If you opt for the type "**Input**" (it means that the user will parameterize a route where the e-mails that need to be read will arrive), it will open new registration fields, such as server, server port, user (e-mail address), password, provider, and inbox folder, therefore it is necessary to fill in the fields; 4. If you opt for the type "**Output**" (it means that the user will parameterize the route where the e-mails that need to be sent from the system will exit), it will open new registration fields, such as server, server port, user, password, sender, set whether TSL/SSL authentication is required (both are security protocols) and user authentication is, therefore, necessary to fill in the fields; 5. Click on "**Save**"; 6. Link the e-mail box to the contract. To do so: Access the functionality `Processes > Portfolio and Catalog Management > Contract` and link the previously registered email box in the "**E-mail**" field and click on "**Save**"; 7. Link the e-mail box to a flow. Therefore: - Access the functionality `System > Flow Maintenance` and when registering/editing a flow, find in the "**Diagram**" filed the figure representing an e-mail in the flow and click on edit; - In the "Configure outbox e-mail" option, opened when clicking on the "**Message**" tab , select the "**Specific**" option to use the mailbox configured in the contract; - Complete the flow parametrization, including the selected "**Recipients**"; - The use of different e-mail outboxes can be noticed after a service request is opened, which has parameterized the flow that has the selected mailbox. - Click on "**Save**". :::hint{type="info"} 🖊 **Note****: **Linking to the mailbox is not a required step. This functionality will only be necessary when registering the flow, the user feels the need to direct the email to an output box different from the default. The system's default e-mail outbox will continue to function even if this setting is not done. :::
