New csf v2.80

Changes:

• Added new lfd feature – Relay Tracking. This allows you to track email that is relayed through the server (cPanel only). It tracks general email sent into the server, email sent out after POP before SMTP and SMTP_AUTH authentication, local email sent from the server (e.g. web scripts). There are also options to send alerts and block IP addresses if the number of emails relayed per hour exceeds configured limits. The blocks can be either permanent or temporary. Currently blocking does not function for LOCALRELAY email.
• Introduced a new blocking mechanism in lfd that allows a choice of permanent or temporary IP blocking. See csf.conf (LF_TRIGGER_PERM) for details on how to configure the various blocking options to use temporary instead of permanent blocks, e.g. for Login Failure blocking
• Modified new installations to default to using seperate triggers for login failures, instead of the global LF_TRIGGER value
