Which MTA/MDA?

Here is my basic setup. I am runing one computer, which runs dual boot XP
and debian. I have installed dsl on a small VM for the purposes of
retrieving, processing and storing it in a folder accessible to both
OSs.

I also expect I will be reprocessing the email later as I refine my
processing rules. Generally the kind of things I expect to do are:
1) Remove duplicate emails.
2) Sort mailing lists into a seperate subfolder.
3) Remove empyt email messages.
4) I want to remove the forwarding messages of messages forwarded from
a different account of mine.
5) Many other that escape my memory right now.


I have many different email accounts oon many different servers.

My knowledge of the MTAs/MDAs out there is minimal. Can someone
I don't want to read the manual of each one that I might use. Can someone
recommend what I shoiuld use?

Thanks
