you probably have a dedicated or real server.

I'm using my workstation to host apache ds.
Currently, I'm suspecting apache ds to answering too fast and 
thunderbird may have an issue with too fast connection.
Using thunderbird to connect localhost service is not the regular case.
In my last message, I was reporting that by emulating network (and not 
localhost), it was functionnal with the same software settings 
(thunderbird and apache ds).
