I am hosting email for a client. They are NOT part of my local network but have a domain and email accounts setup on my SME 6.0 server. When they try to send outbound email they get the following error
"Domain not in list of allowed RCPT hosts - SMTP 553" error.
How do I allow them to send email from their network using my SME server?
Inbound email is working fine. I understand that the problem I am having is done by design in SME to prevent relaying, but I still need to allow these users to be able send outbound email if they are authenticated. I dont' want to specify each domain that they can send outbound email to. I need it to be any outbound domain. Is this possible in SME?
Thanks in advance
