SMTP Server

The SMTP Server page allows you to configure a Simple Mail Transfer Protocol (SMTP) server. Once you configure an SMTP server, Nessus can email HTML scan results to the list of recipients that you specify in the scan settings.

The following table describes the SMTP Server settings:

Setting	Description
Host	The SMTP server host.
Port	The SMTP server port.
From (sender email)	The email address that shows as the sender in the scan results email.
Encryption	The email encryption type: No Encryption — Nessus does not encrypt the email. Force SSL — Nessus forces SSL encryption for the email. Force TLS — Nessus forces TLS encryption for the email. Use TLS if available — Nessus uses TLS encryption if the receiving server is compatible.
Hostname (for email links)	The hostname that shows for the sender host and port in the email.
Auth Method	The authentication method Nessus uses to connect to the STMP server: NONE — Nessus does not authenticate the connection. PLAIN — Nessus secures the connection with plain (username/password) authentication. LOGIN — Nessus secures the connection with login authentication. NTLM — Nessus secures the connection with NTLM authentication. CRAM-MD5 — Nessus secures the connection with CRAM-MD5 authentication.
