[Users] Ghost emails / very strange POP behavior

[Michael]

Ralf,

that's another idea ... a GUI problem. First of all, i use Quicksearch very rarely, and it definitely wasn't activated that time, and for a long time anyway.

The mails in question get filtered into a main folder filled with hundreds of private mail, so, clearly the mails of this folder were not set "invisible" altogether. But is there any GUI way to make a certain thread 'invisible' ?? Not just collapsed.
