Mail Relay

This section provides instructions for configuring the mail service, as well as for using additional features, such as webmail, spam checking, mail relay, forwarding, etc.

All mail traffic filtering capabilities can also be applied to an internal mail server by publishing it via a mail relay.

To configure the mail server in the SafeUTM web interface, go to the Mail relay menu. This section contains all the key parameters that affect mail service work. All configurable parameters are divided into several categories. Each section of the mail server is described below.

If you use the SafeUTM mail server as a full-fledged server with mail storage, it is mandatory to store mail on an additional HDD/SSD drive. Connect an additional hard drive to the server before using mail.

When configuring the cluster, mail will be available for operation only in the mail relay mode. Mailbox storage is disabled.
