Doing a quick search on Google for that error message "MX points to hosts without valid addresses." brought up a few results.</p> <p>Here is one:</p> <p><a href="http://forums.devshed.com/mail-server-help-111/mx-issue-and-getting-pushed-back-313376.html" rel="nofollow">http://forums.devshed.com/mail-server-help-111/mx-issue-and-getting-pushed-back-313376.html</a></p> <p>The recipients email server is configured in such a way that it has very strict rules so something with your server setup is causing it to reject the email. </p> https://legacy.forums.gravityhelp.com/topic/question-about-bounced-messages#post-4428 Fri, 02 Apr 2010 15:05:31 +0000 Wheaton College 4428@https://legacy.forums.gravityhelp.com/ <p>Carl, thanks for getting back to me. We're using a standard WordPress MU install. No SMTP plugin. </p> https://legacy.forums.gravityhelp.com/topic/question-about-bounced-messages#post-4425 Fri, 02 Apr 2010 10:45:02 +0000 Carl Hancock 4425@https://legacy.forums.gravityhelp.com/ <p>Are you using a WordPress SMTP plugin to send email or are you using a standard WordPress install with no SMTP plugin? </p> https://legacy.forums.gravityhelp.com/topic/question-about-bounced-messages#post-4421 Thu, 01 Apr 2010 20:18:05 +0000 Wheaton College 4421@https://legacy.forums.gravityhelp.com/ <p>Hi, I know this isn't an email server support forum, per se. But I am wondering if GF has any settings that might help.</p> <p>Most email sent from GF goes through just fine.</p> <p>Some messages are bounced back with this error:</p> <p>Subject: Mail delivery failed: returning message to sender<br /> <a href="mailto:recipient@email.com">recipient@email.com</a><br /> SMTP error from remote mail server after MAIL FROM:&lt;webserveruser@web.host&gt; SIZE=9997:<br /> host mail-relay.msln.net [130.111.32.28]: 550 5.5.4 &lt;webserveruser@web.host&gt;... Domain of sender address <a href="mailto:webserveruser@web.host">webserveruser@web.host</a> refused. MX points to hosts without valid addresses. This violates RFC 1035/2181.</p> <p>Any clues as to how to fix this? Thanks. </p>
