Hi
We are using Lotus Domino 6 Mail Server, it is running on Red Hat Linux 7.3 O/S.
When our users send mails some address, some time it will return and give this error massage
“Error transferring to DEBUGISP.NET; SMTP Protocol Returned a Permanent Error 550 5.7.1 … Relaying denied”
When I resend this mail I can not send again it will return. What is the Problem How can I sovle this Problem
Thanks
