Netgate is offering COVID-19 aid for pfSense software users, learn more.
pfSense® software notifies the administrator of important events and errors by displaying an alert in the menu bar, indicated by the icon. pfSense can also send these notifications remotely via E-mail using SMTP.
E-mail notifications are delivered by a direct SMTP connection to a mail server. The server must be configured to allow relaying from the firewall or accept authenticated SMTP connections.
- Disable SMTP
When checked, SMTP notifications will not be sent. This is useful to silence notifications while keeping SMTP settings in place for use by other purposes such as packages that utilize e-mail.
- E-mail server
The hostname or IP address of the e-mail server through which the notifications will be sent.
- SMTP Port of E-mail server
The port to use when communicating with the SMTP server. The most common ports are 25 and 587. In many cases, 25 will not work unless it is to a local or internal mail server. Providers frequently block outbound connections to port 25, so use 587 (the Submission port) when possible.
- Connection Timeout to E-Mail Server
The length of time, in seconds, that the firewall will wait for an SMTP connection to complete.
- Secure SMTP Connection
When set, the firewall will attempt an SSL/TLS connection when sending e-mail. The server must have a valid SSL certificate and accept SSL/TLS connections.
- From e-mail address
The e-mail address that will be used in the
From:header, which specifies the source of the message. Some SMTP servers attempt to validate this address so the best practice is to use a real address in this field. This is commonly set to the same address as Notification E-mail address.
- Notification E-mail address
The e-mail address for the
To:header of the message, which is the destination where the notification e-mails will be delivered by the firewall.
- Notification E-Mail Auth Username
Optional. If the mail server requires a username and password for authentication, enter the username here.
- Notification E-Mail Auth Password
Optional. If the mail server requires a username and password for authentication, enter the password here and in the confirmation field.
- Notification E-mail Auth Mechanism
This field specifies the authentication mechanism required by the mail server. The majority of e-mail servers work with PLAIN authentication, others such as MS Exchange may require LOGIN style authentication.

If the firewall hardware has a PC speaker pfSense will play a sound when startup finishes and again when a shutdown is initiated.
Check Disable the startup/shutdown beep to prevent the firewall from playing these sounds.
