Hello, i have notice something embarassing.
When i copy a message from some Folder to Sent Folder, there i a display problem.
In Sent folder the mail is showing To the sender and no the Destinatary...
From example:
If i have a mail From= john To=David in some folder... when i copy this mail in Sent Folder it is display To=John in the principal page...
But when i open the mail, From: and To: are good...
A screenshot is more clear...
After copying message from folder to "Sent" folder the dysplay To is wrong
You can see on the screen, that the mail is From=Jean Luc To=Pierre
But in the principal dysplay there is To=Jean Luc
