I got a map called “Dumpster”, and it is filled with messages I deleted long time ago.
It is impossible to delete messages in the map or the map itself. 
I am using Tele2 as e-mail server, and Tele2 don’t care to answer. 
Any suggestion?

I think by Dumpster you mean Trash. :wink:

Right-click on the Trash folder and choose Empty Trash.

Thanks for replay.

That is not something created by eM Client. It comes from either your provider, or another device like a phone that also connected to your email account.

I will choose another provider
