We have a client that is not receiving emails that our webserver is sending to them.
Our server is not blacklisted, nor is it an SPF issue. Emails are being delivered to every domain except for them.
I'm talking to their IT guy right now - and he's saying that his suspicion is (because there is no record that the emails have ever hit their server) that we are not sending to the right MX record for their domain.
Now - I'm not really a DNS/Server guy (my thing is software) - but that doesn't make sense to me.
Correct me if I'm missing something...
We (my server) have nothing to do with the MX record of your server. Nor do we have any control over what MX record is being sent to. That's handled specifically by your DNS. As such, we have no control over how the email is routed...as that's controlled specifically by your nameserver/DNS records you've set.
Isn't that correct? Or - is there something we can do on our end that I'm somehow missing?
