Failover SMTP Smarthost with PFSense

Posted: August 5, 2015 in Netwok

This solution if we want use 2 smtp smarthost (failover) as sender email.

– Install Postfix Forwarder


– Open Postfix Forwarder (Services –> Postfix Forwarder)

type on custom options

relayhost = [smtp.smarthost1]
fallback_relay = [smtp.smarthost2]


When connection smtp.smarthost1 Down, email send from smtp.smarthost2. If connection UP, email send from smtp.smarthost1 again.

– Give permission server can relay to PFSense (send email through PFSense)
