For the emails sent out from TRIRIGA, the sender email address is defaulted to SYSTEM@[hostname]. For my current situation, the hostname is not a publicly available domain, only an internal development server. The emails are received by Google Mail and Yahoo Mail, but not being received by corporate email hosts. I suspect it is because of the invalid hostname and rejected as spam. I’ve tried to set the “mail.smtp.from” property in the WebSphere Application Server Admin Console, but it is not working. Any suggestions?
