Sheriff CSM™

Configure Mail Relay in Sheriff CSM

You can configure to receive emails from Sheriff CSM. For example, if you want to receive an email when an alarm appears, you can create a policy for the email to be sent. For details, see Tutorial: Create a Policy to Send Emails Triggered by Events. But first, you need to configure mail relay in Sheriff CSM.

Sheriff CSM uses Postfix, an open-source mail transfer agent (MTA), as Simple Mail Transfer Protocol (SMTP) Server for outgoing messages.

Sheriff CSM SMTP Server Default Settings

Protocol	Port Number	Notes
SMTP	25	This is the port number assigned to SMTP and used for mail server relay. Note that most Internet service providers (ISPs) block this port to curb the amount of spam they receive.
TLS (Transport Layer Security)	587	This is the default port number that Sheriff CSM uses to send outgoing messages. The connection is encrypted by executing the STARTTLS command.

Sheriff CSM also enables the following properties from Postfix:

smtp_sasl_auth_enable = yes 
smtp_sasl_security_options = noanonymous
smtp_sasl_tls_security_options = noanonymous</span>

This means Sheriff CSM enables Simple Authentication and Security Layer (SASL) authentication for SMTP, denying anonymous authentication.

Mail Server Relay Configuration

For simply receiving emails from Sheriff CSM, you do not need to set up mail server relay. However, if your company has a dedicated mail server that you want to keep using, you can configure Sheriff CSM to route emails through your corporate mail program. To prevent such messages from going to your junk mail or spam folder, you can add Sheriff CSM as a safe sender for Office 365 or add it to the email whitelist for Gmail.

You perform this task on either a Sheriff CSM All-in-One or a Sheriff CSM Server.
