thanks for your reply, I'll check for this.
In my understanding, when a packet passes through the firewall with a port forward, the packet retains its src address. Am I wrong ? This "open relay" problem is causing me some headaches...
Is it possibile to completely disable open relaying, leaving this feature only for localhost (webmail) ?
Thanks !
