HELP! Email not sending from server / 550 - Verification/Sender failed

Posted by doulos, 09-13-2011, 12:46 AM

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 - I then ran and exim command to check the two accouts and got this result - Any suggestions? Thanks, D.

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

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