Clients cannot email to Exchange Server
I have a client(clientA) that uses an exchange server for their email, and hosting is with me. I set up an A record for them that points to their email server IP address. ClientA recieves all emails from email accounts outside of my server. However, I get bounceback messages when i try to send emails to clientA from any of my clients that are hosted on my server.
I am running RHEL3 and DNS, etc
Can someone please help
Thanks,
Matthew
