well most networks have a hub of which the IP is unknown to the public, so during a possible ddos they wouldn't be able to attack the hub and thus disrupt the entire network by taking a single server offline.
I do the same, however there is a leak in the security... when you request a sendpass an email is send with sendmail, and the IP of the originating box can be found in the headers if that email.
chaz told me about anopesmtp and i replaced the sendmail line on my testnet with the following:
SendMailPath "anopesmtp 193.74.71.25"
where 193.74.71.25 is my isp's smtp server.
For this to work on my production network, there is an smtp relay setup on another box set to allow smtp traffic from my hub.
Problem is now that i can't even get it working on my testnet by simply specifying my isp's mailserver..
anyone who can help me out ?
