I face an issue of sending email using Outlook via smtp.streamyx.com while connecting to Digi EDGE network. I have tested around and able to solve it for time being.
The trick is hange your SMTP server to roam.tm.net.my and still check on Outgoing mail needs authentication. I tested the connection, it is able to connect to SMTP server but test mail has failed. When I try to send out an email, it still able to get through. So, it solve my problem and should work until TM make some stupid changes.
