spf question!

There is one outsider wanted to send an email to one of my users and he received an error message bounced back.

Then I asked him to forward the error message to me. The message is long but there is one line (below) that I want to know. Can someone interpret this for me? Thanks,

Received-SPF: none (0: domain at htaew.com does not designate permitted sender hosts)


Thanks,

spf stands for 'sender policy framework'. it's basically sender authentication that should allow spam filters to help cut down on spam in the future by adding a way to verify the details in the SPF record.

here's some more info:

What should I tell the sender to succesfully send the message to my user.

i don't believe anything to do with that line is what's causing the problem. very few ppl utilize spf yet anyways, and the line above simply iterates that you're not using it 'does not designate permitted sender hosts'.
is htaew your domain or his?

he was trying to send an email to one of your users (same namespace, usera@domain.com), it bounced back to him, yet he was able to forward the NDR to you (same namespace, userb@domain.com) with no problems?

could have been something intermittent on his end. I would have him try it again. if it still fails post the complete NDR.

I believe you need to create a reverse DNS lookup record for your mail server in the internet DNS servers.  Anyone using SPF should then be able to e-mail you.

I would imagine that everyone will be using SPF within a few years so it's a good idea to get the DNS record in place for the future anyway.

The htaew is his side.
He was trying to send my user an email, it bounced back to him with an erroe message. He then forwarded the error message to me with no problem. Below is the error message that his server sent to him. His name is Terry. Please pay attention to this line. "Article rejected due to incorrect password".

So you've been having this issue with this domain since last July?

If you run his domain through dnsstuff, check the 3rd warning from the bottom:

http://www.dnsreport.com/tools/dnsreport.ch?domain=htaew.com

this would be my best guess as to what is causing the problem. He needs to fix his setup so that everything checks out OK. Your simscan product could very well be rejecting his mail for this reason.

hth,
Kris.

I really don't know. He sends out the email to whole bunch of addresses, only my user's address causes the return.

try adding his domain as a safe sender in your simscan product. you're going to have to do a little bit of work if you want to figure this out, and he might as well.

in addition to all the things i've outlined you could also try looking at firewall logs at both ends to see if the email even makes it out of his org (or into yours for that matter).

or have you checked your simscan logs?

what troubleshooting steps have you taken thus far?

Instead of emailing my use as part of the mailing list, I told the dude to email my user individually by typing his address and cc to me, we both received the email.

What is up?

Thanks,

It is impossible to say. You aren't providing enough information for me (or likely anyone else) to answer that question.

also, you didn't answer any of the questions or say if you tried any of the suggestions i detailed in my last post.

Aaaaahhh, I am sorry for the delay. I am troubleshooting the problem. I am working with my ISP to see if anything got blocked at their end. The email did not even get to my ISP. I am viewing the firewall logs as well as my Mdeamon logs. Did not see anything either. I am sending all my DomainPoP.log to a Mdeamon support group for them to to view.
Please allow several more days.
