# Setting Up Outbound Mail Connections
Using the mail receiver adapter, you connect the tenant with an e-mail server so that the tenant can send emails to the e-mail server.
In other words, the tenant sends a request to the e-mail server, and the data flow is in the same direction, from the tenant to the e-mail server, as illustrated in the figure. The direction of the request is indicated by the arrow next to the *R* notation in the following figure, the direction of the data flow by the direction of the connection arrow.
Using the mail receiver adapter, you can connect to mail servers through the SMTP protocol.
The following table lists the options for setting up secure connections. Consider the following table as a connection setup checklist. For a detailed description of the available properties for integration flow design, see the documentation of the individual adapter.
