it sounds like DNS record issue to me... when people send you an email to your Exchange server, basically DNS server has to know that you have MX record which is identified all around the world by every DNS server so it will bounce it to proper server.

Do you have your own DNS server ?
Does your Exchange sever has MX record with DNS server ?
Is your Exchange server behind a firewall ? if so, do you use NAT ?
