Public email servers working in 2020?

Post by bradetter »

Evidently, public email servers have tightened their security and caused problems for many IP cameras and NVRs.
I am still working with Amcrest support; however, I'm not very optimistic.

Has ANYONE been able to send emails to ANY email service lately?
I have tried both Yahoo and Gmail with all variations of ports, lowered security, etc.
It would help if the NVR generated some info in the system log for these types of issues.

Thanks in advance.

Microsoft's servers still work since they ignore the invalid TLS handshake that the Amcrest devices are using. Long-term you'll have to either track down more and more obscure mailers that will still accept the invalid TLS handshake or set up your own mail relay that takes incoming messages from Amcrest devices and forwards them on using a correct TLS handshake.

On the basis of "if they can't get their s**t together maybe we can get it together for them", I had a look at what it'd take to fix the TLS bug. The idea is to patch the binary so the SCSV signalling value gets turned into something else which is ignored by the server. The firmware is a squashfs busybox image which can be unpacked to yield the TLS code, which was in some subdirectory I can't remember, can't access the Linux box I did it on from here. To fix the bug, you patch out the cipher suite 0x56 0x00, e.g. by changing it to 0x57 0x00. However, the firmware is signed so you then have to patch out the signature check as well. I found the crypto code in IDA Pro but ran out of time, and was also somewhat less motivated about flashing patched custom-assembled firmware into the NVR that I need to use for security purposes.

Well if you get a email from a Test then you should have no issue getting the email from the DVR/NVRs and or IP cameras event. Setting up the email server isn't only thing you have to do, In some devices on the email page you have to enable it. In all devices you have to setup for what event you want email for. So take my DVR, setup for email, I want events emailed from my recorder on a Tripwire event, So I go to the channel with Tripwire setup and I click the email box and then when there is a trigger for that tripwire I will get an email. Then on the SMD page if I want an email for that again I go to the page on my DVR for the channel I want the email from I click that and now all events SMD for that channel I will get an email for..

Now on my Driveway, I have it setup for 2 different tripwires for one of my cameras, On that I have it setup that I want emails for humans that are coming into my Driveway.. If I had it setup with only 1 tripwire and setup for email I get both humans and vehicles, this way with 2 tripwires I get only emails when a human comes down my Driveway..

I would double check that your email is in fact enabled and that you have also setup the event you want emailed to you has a check mark..
