I have already been into BIS and created the filtr to stop my sent emails being sent to me. That worked perfect for a month or so i had no issues.
Now all of a sudden, since upgrading to latest OS, I will read an email someone sends me, and then either an hour, or few hours lter i will get the same exact email again. Sometimes a 3rd time.
What can i do to stop this? It did not occur until i upgraded.
