How can I prove him wrong? I know that there are SFP records out there for our email domain. (Mail.ourdomain.com) 12.123.123.123 but the information that the recipient is providign to us shows that SPF lookup is failing on mailsweeper6.ourdomain.org<wbr /> which is our mailsweeper appliance. Why is his SPF lookup looking at this internal address?<br />
<br />
The recipients IT staff (Hosted email by DNSPark) keeps thrwoing it back in our lap saying the problem is on our end. I am not quite sure what tool I can use to prove that a SPF lookup on our mail domain is valid. I also don't understand why they are doing a lookup on the server name of our mime sweeper box?<br />
<br />
The recipient's IT department replies with:<br />
&quot;&nbsp;The sending server admin needs to ensure that their sending IP/host is listed in the SPF record for whatever domain is used to send mail. That is the quickest route to resolution of this issue.&quot;<br />

Can you help Please?

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.
