I am using Office 365 product. So my current issue is I want to send test mail using Telnet and the error appear 530 5.7.1 Client was not authenticated. I have ePortal system and configured Email notification. After configuration done I
try send test mail from ePortal. The error appeard "504 Unrecognized authentication type". The best way I try troubleshoot this issue is using telnet command. By telnet command I also got the error as below,
