Spf

I have no idea if this is the forum to ask this question; but here goes.

I'm getting hundreds of bounced e-mails. Six thousand a day is not uncommon. The problem is that my domain name is being spoofed.

Has anyone had any experience with SPF

This seems to be the ideal solution, even though it is not complete.

Thanks

AFAIK, unless the mail servers taking the deliveries of the forged emails are using SPF as well, you will still probably get the NDRs.

If I understand the technology correctly...

True, but it looks as though some big players are in this game.

AOL for one and at this point even partial relief is better than none.

Sometimes the original headers get send along the NDR. Can't you trace one of those to find the culpret?

The culprit is

name@co - co cc

name can be any combination found on your keyboard.

with link to www.blyadi.biz which goes no where.

Aren't there any headers in those NDRs? A source email address is useless as it's probably spoofed.

Have you tried contacting the party that sends you the NDRs? Maybe you can work with them to trace it from their side. They'll probably have some problems to.

192.168.100.200

That number does not exist on any of my internal domains. And it should not appear at all. I thought that number would not go across the Internet, but obviously, I am wrong. Or someone knows how to spoof an IP number.

The forwarding mail server looks like--
adsl.nuria.telefonica-data.net at 80.28.152.240

Tried pinging that number no responce

Sounds like a spanish DSL user to me.
Can you post one of those NDRs here? Only remove the addresses that belong to you.
