First, sorry for my langage, I speak english just a little.
Next, I use Syncback free since many years without problems, but I have a problem with email log since few months
Impossible to send it. First send by gmail adress without problems while a year, and impossible to send... I create a new mail adress on GMX.fr... Never worked. New Yahoo adress, never worked too, new Mail.com adress, it worked... 3 times
I'm really sick of this
I use V9.0.8.15, but it's the same with previous versions
If it helps you, test log with Yahoo mail:
