<p>No, "empty subject" is irrelevant... Much more likely that either of the two MTAs (at least two;-) are the culprits... Either it never leaves the sender properly, or your upstream ISP is dropping it. Have you talked to a technical contact at either org?<br>
Does the sender receive any delivery report (have them check any junkmail folder)?</p>
<p>Cheers!<br>
