Email log send fail

SyncBackFree is the freeware version of SyncBack. It is *not* an evaluation version of SyncBackPro/SE.

Email log send fail

Post by Kingus »

Hello,

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:
