Being unsuccesful in connecting to our SMTP server with the DR4100 through a portforwarding server I set up the same server to act as a NAT router. This gave me half success, I now can see connections being made at our SMTP server. It appears that for the e-mail alert service to work correctly, the DR4100 configuration must meet the following requirements (not mentioned in the manual) So, for the other half of the story; the unsuccess one:The e-mails are getting stuck in our spam filtering since it (rightfully) doesn't recognize the sending address of root[NAME].ourdomain.com Is there really no way of altering the sending address? I cannot find it.If there isn't, please add this as in future updates.
I've setup a DR4100 and it is mostly working great.One thing I cannot get working though is the email alerts.There is a Recipient address, an Email Relay Host  and Admin Contact info (which I assume is the sender address used) configured. The unit itself resides on a IP subnet with no routing to the outside world, so the Email Relay Host is pointed at the IP address of our backup server, also with an interface on the same subnet. On the backup server (Windows 2012R2) there is a portforwarding done (to a SMTP server) with "netsh interface portproxy", a setup I've used in many similar cases.I can not see any connection attempts (TCPView) on the backup server from the DR4100, nor can I see anything in the SMTP servers logs. The DR4100 itself says "Successfully sent email to all recipients" and the event log says "Test email sent".Is there any other log on the DR4100 that could show what's really going on, or how should I solve this mail alert problem?
