Am getting an error "Server error: '550 5.7.1 (email address here)... Relaying denied. IP name lookup failed", whenever I try to send any email from Microsoft Outlook.
I think the issue is something to do with SMTP server???
I checked the account in Outlook and it reckons it sent a test message successfully, but I still have the problem.
How do I fix this problem?
