@Arianna I'm getting the exact same error message also every 15 seconds. TP Link chat support was  no help only suggesting resetting the camera, and if the problem still exists, changing roughter DNS. I believe this error is not affectiong any functions, however do not want it to continue filling the system log. Issues like this should be addressed as soon as possible... as it is a background task erroring out. I wouln'd hold my breath for a system update on such old hardware now and would guess firmware for the NC200 is no longer supported. What a mess they have left this product in. Another case possibly of not fully testing firmare before release maybe. TP-Link, please re~visit this firmare and have it runnig the way it should... this error is doing OUR heads in obviously. We have completed paying for your product, please complete servicing the the product to it's correct functional state. Asses...

I upgraded to:

Dare I say that item 1. Fix bug of SMTP Notification was not addressed.

And this f'n firmware can't be downgraded.

I think possibly the best we can hope for is 3rd party software/custom firmware. *shrug*

If anyone stumbles accross any stable custom firmware solutions, please reply.

Peace.

I gotta go, my spare time is now needlessly taken up clearing out f'n endless System Log SMTP Errors!
