We are not able to send message to one client domain and we are getting an error message that says "The following recipient(s) could not be reached:
user@clientdomain.com.au on 15/10/2007 11:33 AM
You do not have permission to send to this recipient. For assistance, contact your system administrator. <domain.com.au #5.7.1 smtp;554 5.7.1 <user@clientdomain.com.au>: Relay access denied>"
But we are able to receive the email from them. If I am trying to telnet their mail server, then 110 is successful but 25 failed. Can anyone tell me which mail server issue is this, is it my client server or only the server? Thanks.
