[CentOS] Using Thunderbird as local mail reader

Hi!

I'm trying to figure out how to use Thunderbird as a local mail reader.

So far I don't see any way to configure it other than as a POP3 or IMAP mail reader,
but I get my mail locally and would like to try using Tbird to read it.
What am I overlooking?

Thanks in advance!
