<p class="MsoNormal">Hi all, </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Sorry for the noise, but one of my clients is getting the standard “it’s the other guy’s fault” with some email delivery issues to/from Proofpoint “Enterprise” customers. If there is anyone from Proofpoint support monitoring this list,
some assistance troubleshooting email delivery issues would be greatly appreciated.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thank you,</p>
