Dear All Greetings,
i am admin for ISP two years now, relay emails for more than 300 companies (CentOS/Postfix). Relaying more than 10,000 messages every hours successfully. no one has ever compliant for non delivery. but i cannot relay to this domain. The servers responsible for accepting messages are rejecting. i have given the whole log for experts to monitor.
it is something out of control, because it is not my problem. Our server has all record created (A,MX,PTR,SPF etc). i have three relay hosts fully functional. destination server is not accepting from any relay host.
can anyone try from his server and see if it is deliverable to ray@tata-nigeria.com
Thanks / Regards Prabhpal S. Mavi
