mails displays as "dummy@example.org" after deleting

Everytime I delete a message, the message is Displayed as “dummy@example.org”. but it’s not deleted properly. this problems occured after the update 6.019660

Yes I am having the exact same issue. It just started with the latest build 6.019660 RC. At first i thought I had some kind of virus because of this dummy message kept popping up. Glad to hear it’s not just me. Must be a small bug in the RC build.

Hopefully this will be fixed soon.

I can not work like that.
Is there goging to be an Upgrade, or do I need to down-grade again?

same issue any solution
