Hi Matheu,

Thank you for that information. I wasn't even aware that this problem 
existed. CleanTalk seems to be the cause of this problem. I will look 
for ways to find a solution.  I can't promise to find a solution 
immediately, it will certainly take some time and testing. I will open a 
ticket and try to solve this problem after my vacation.
