Hi, We do have some problem upon mail synchronization between CPanale mail ( my mail server) with Thunder bird ( on my laptop). We have found that when we access my mail server ( CPanal ) directly and   delete some mail, that mail ( In my Thunder Bird mail box - upon my Laptop) will be automatically removed from my Thunder Bird mail on my Laptop. I want to delete file from mail server without any automatically synchronize delete file in my Thunder bird. How can i set up Thunder bird?
