I am working with a server that has CentOS 5 which uses Virtualmin to configure the server. I run a similar configuration with no issues. When DocuSign sends us a message, the maillog has this in it:
Oct 29 12:09:32 saguarogold postfix/smtpd[10387]: NOQUEUE: reject: RCPT from mailch.docusign.net[206.25.247.155]: 451 4.3.5 Server configuration problem; from=<dse_...@docusign.net> to=<j...@goldsavings.com> proto=ESMTP helo=<mailch.docusign.net> Odd thing is that an identical server which has Eudora Internet Mail Server on it, receives similar emails from them fine. Here is the result of postconf -n. Not sure what the issue is. Perhaps its staring me in the face.
