Mail Notification

Introduction

Mail notifications (also known as Mail Relay) allow you to send email from the Security Gateway.

You can send email interactively or from a script. The email is relayed to a mail hub that sends the email to the final recipient.

Mail notifications are used as an alerting mechanism when a Firewall rule is triggered. It is also used to email the results of cron jobs to the system administrator.

Gaia supports these mail notification features:

  • Presence of a mail client or Mail User Agent (MUA) that can be used interactively or from a script.

  • Presence of a Sendmail-like replacement that relays mail to a mail hub by using SMTP.

  • Ability to specify the default recipient on the mail hub.

Gaia does not support these mail notification features:

  • Incoming e-mail.

  • Mail transfer protocols other than outbound SMTP.

  • Telnet to port 25.

  • E-mail accounts other than admin or monitor.
