RT-AC87U - Does Feedback work?

Hi,

Currently on 3.0.0.4.382_50702 f/w. The feedback doesn't go through. It errors out with this message

The system failed to connect to the mail server(possibly caused by your ISP blocked SMTP port 25

I don't see the Asus mail server listening on 25. So it wouldn't work unless they update the port in the f/w.

Has it worked for anyone?

Thanks
