Dahua NVR Stopped sending emails

It works for me with a new Yahoo account.

SMTP Server: smtp.mail.yahoo.com
Port: 587
Username: myemail (without @yahoo.com)
Password: my password email
Sender: myemail@yahoo.com

Authentication: TLS
Title: Dahua alert
Mail receiver: My other email

You have to change Yahoo Security settings to allow less secure apps.
 
Dahua have finally released a firmware update for NVR4XXX series NVR's that addresses this issue. Using the built in upgrade checker does not find this update, you have to download and install manually here:

and select the file dated 02/08/2019.

I have just installed the firmware on my NVR4204 and Gmail now works again!

My settings as follows:
- Username: your gmail address
- Sender: your gmail address
- Encryption: TLS
- Port: 587
- SMTP Server: smtp.gmail.com

They (the 4xxx series) are notorious at killing USB sticks (mine has destroyed 3), so check for errors on it. Seriously, switch the nvr off before removing the usb stick is a good idea...

I saw that Dahua provided updates to fix problems with email notification for gmail for some NVRs and XVRs. So I emailed support regarding my DH-IPC-HFW1320SP camera and got this reply,:

I'm not quite sure to make of this - could be my Ebay purchase was of a knock-off, or a genuine Dahua geared for a non US market - could be that Dahua knows nothing about the gmail problem for IP cameras. Heck if I know! But, yahoo is still working for me, so I'm good. But, it would be nice to use gmail again.

Have you set up firewall rules to block LAN to WAN traffic/closed all the ports?

If so, the camera/app may have lost the ability to resolve smtp.gmail.com, hence won't be able to send the emails.

For me, making a rule to allow TLS/port 587 was not enough. I also had to make a rule to allow DNS/port 53. As well, the port 53 rule had to be before the port 587 rule.

I'm not sure if you're still active here since on my end it says you're last activity was last year at March but anyways, I was wondering, would you be able to explain to me on this rule for allowing the Encryption type and port? I'm having issues with mine and I'm using Yahoo with SSL + Port 465 but I did not do any rule things.
