I have 3 questions;
1) Is there any way/program other than iptables to bind an IP to a MAC address bcoz i have certain machines on my network to whom i allow unrestricted access to certain resources and i want to avoid IP spoofing. I can do with iptables but jus wannan know alternate ways
2) I use qmail-scanner with clamav and my company's policy is to reject certain extensions like archive extension (zip,rar etc) as attachments. But i find it can be easily bypassed by changing the file extensions to say an allowed extension like .doc . how can i stop this.
3) Is there a browser based program like this:
that will let my users change thier qmail (smtp/pop) password remotely. Currently i'm using OmailAdmin but i wan't just a simple password change only webpage.
