I am responsible for IT for a small charity and we have a problem with a few individuals who e-mail us on our hosted e-mail addresses. The individual is on btconnect and our server is also on BT broadband and using MSExchange. I understand that the message from firstname.lastname@example.org are generated by Exchange but can't tell whether this is a problem with our server (seems unlikely as most people send and receive e-mails perfectly well) or with the sender's server.
I have copied a sample test message below and would be very grateful if somebody can explain what is causing this problem.
I have * the personal details - hope that's acceptable but I don't want to compromise the individual's identity/security.
