Every time I recreate my singnatures and rules in my Mail application, they disappear and need to be recreated.
This only happened since the Mavericks "update".
Apple does not seem to have a solution to this and it is becoming annoying beyond despair. I might even remove Mavericks altogether and go back to the previous system as not only will it ensure my email signatures remain, but my battery life will suddnly jump BACK to being 12 hours on my MacBook Air.
What are Apple playing at? Come back Steve Jobs....
