Re: a creative idea against spam emails

Frankly, it's useless IMO.

- it's ok to add extra layer on your own server, or extra workload to yourself (as a sysadmin), but never bring any extra workload to  sender and receiver. Treat sender and receiver as non-tech person, they don't understand much tech things.

- email headers are too easy to forge, consider this when design your anti-spam method.

Re: a creative idea against spam emails

Thank you for your reply. But I think my tech has its own value. No complex filter design, but simple and straight pass code filter. The workload added on mailserver is very mini.
