Global

On the Email Protection > SMTP > Global tab you can decide whether to use Simple mode for SMTP configuration or Profile mode.

  1. Enable SMTP.

    Click the toggle switch.

    The toggle switch turns green and the Configuration Mode area becomes editable.

  2. Select a configuration mode.

    Simple mode: Use this mode if all domains share the same settings. However, you can still define exceptions based on domain name, email addresses, and hosts. There is no functionality restriction compared with Profile mode.

    Profile mode: (Not available with BasicGuard subscription.) In this mode you can override or extend global settings e.g., of antispam and malware, for individual domains or domain groups by creating profiles for them in the menu SMTP Profiles. Settings made in the SMTP menu still apply to their assigned domains and, moreover, serve as defaults for profiles. In Profile mode, you will find additional notes with some of the settings regarding recommendations for profile mode and behavior of Sophos UTM on AWS.

  3. Click Apply.

    The selected mode will be enabled.

Listen Interfaces

By default, the SMTP proxy listens on all interfaces on ports 25, 465, and 587 for incoming email traffic.

To listen only on particular interfaces, select the option Custom Interfaces and add interfaces to the Allowed Interfaces box. Click Apply.

SPX Global Template

If SPX Encryption is enabled, this section is available. From the drop-down list, select the SPX template that will be globally used. If using SMTP simple mode, this template will be used for all SMTP users. If using SMTP profile mode, this template will be used for all SMTP profiles that do not have an individual SPX template selected.

Live Log

The SMTP Live Log logs the SMTP proxy activities, showing all incoming emails. Click the button to open the live log in a new window.
