I have no idea.   I don't get descriptive errors from the device, all I get from the NAS is "Failed to send message", the router gives no message at all when it sends an alert and it fails, and the Health monitor software gives "Failed to send alert" message too.   I haven't tried setting up an email client on their remote desktop server, but I'm really getting frustrated because I know it's on their end.  

What's happened in the past is Optimum will turn off port 25 to prevent spam flowing through their system, but they swear our stuff is wide open and I can send to another SMTP server that's built into the NAS.

It's like their mail.optonline.net SMTP server now requires authentication or something but they're telling me that's wide open as long as we're physically connected to their network.

Sounds like the server got on the blacklist. Are the messages going straight to spam/junk?
