Sorry I’m new to this.
I posted that I couldn’t send messages without getting an error but I cant find the post.
I consulted with the guru at my isp and I went to settings and upgraded my passwordon the outbound server.
I was then able to send messages but still got the error: " Failed to send some messages.server only accepting messages from authenticated sources".
But then I would spontaneously periodically get the same error message.
I figured that it was the same periodicity as my fetchcycle.
I went to settings and upped my fetch frequency.
the messages ceased unless I forced an update.
I have a Motorola X3 upgraded to the highest Android.
I Have the latest and greatest K9.
