HELP! Email not sending from server / 550 - Verification/Sender failed
Started having email issues on my server last Friday. Several clients reported that the Mailer-Daemon was bouncing back emails. SO I tried of two different hosted accounts to send email with a test account I set up. I got the same result off of both, even after restarting Exim. Here is the bounce back email -
Code:Subject: Mail delivery failed: returning message to sender This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: jschup@sx.com SMTP error from remote mail server after RCPT TO:<jschup@sx.com>: host sx.com [209.xxx.xxx.xxx]: 550-Verification failed for <jstest@testhost.com> 550-No Such User Here" 550 Sender verify failed ------ This is a copy of the message, including all the headers. ------ Return-path: <jstest@testhost.com> Received: from localhost ([127.0.0.1]) by server1.com with esmtpa (Exim 4.69) (envelope-from <jstest@testhost.com>) id 1R3FkQ-0001PN-6f for jschup@sx.com; Mon, 12 Sep 2011 18:16:43 -0500 Received: from 99.xxx.xxx.xxx ([99.xxx.xxx.xxx]) by 64.xxx.xxx.xxx (Horde Framework) with HTTP; Mon, 12 Sep 2011 18:17:06 -0500 Message-ID: <20110912181706.66494ty53ckwhr00@64.xxx.xxx.xxx> Date: Mon, 12 Sep 2011 18:17:06 -0500 From: jstest@testhost.com To: jschup@sx.com Subject: Email test2 MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; DelSp="Yes"; format="flowed" Content-Disposition: inline Content-Transfer-Encoding: 7bit User-Agent: Internet Messaging Program (IMP) H3 (4.3.9) Email from cpanel off of the server
Code:[root@server1 /]# exim -bt jstest@testhost.com jstest@testhost.com router = virtual_user, transport = virtual_userdelivery [root@server1 /]# exim -bt jstest@testhost2.com jstest@testhost2.com router = virtual_user, transport = virtual_userdelivery
Thanks, D.

Hello
Please ensure that the sending domain/server has a valid rDNS (PTR) record and is not listed in RBL.Fred Bruner

Look what server is telling you:
"550-No Such User Here"
Which means user "jschup@sx.com" was not found in the mail server.
