Shouldn't be hard to fix that - they just need to keep track of the originating SMTP server of the first e-mail.

- drm237 18y agoSince many large email providers use clusters of smtp servers, it's probably better to try to use SPF records or Domain Keys signing leaving the originating smtp server as a latter resort. Even reverse dns lookups might be partly helpful but if someone controls the ip they could change that easily... Interesting problem over. I love the service though. Congrats guys!
- tlrobinson 18y agoAnd what happens if you use gmail or any other large email host?
- nickb 18y agoHow will you get <fake>@gmail.com?
- tlrobinson 18y agoI wouldn't be surprised if there are large hosts that don't check for spoofed "from" addresses. Maybe not Gmail, but I haven't checked.
