Smarthost is rejecting all the Mails if the Primary MX is down!
I have setup a Mailgateway (Spam and Virusfilter) based on the 2 Howto's "Virtual Users and Domains with Postfix, Courier and MySQL" and "How to Fight Spam Using Your Postfix Configuration"... This configuration works really fine for me accept to one thing. The Mailgateway relays mails to my internal Mailserver but when the internal Mailserver is down the sender gets a ‘Mail can not be Delivered’ Error message. So my question is it possible to configure the Mailgateway to keep the mails in Queue and deliver them later when the internal Mailserver is up again instead of sending back the error Messages.
