Recommend an email program for the debian-user-digest?

[DJ Hackenbruch <djhack@assisttoweb.com>]

Can anyone recommend an email program that works well when dealing with 
messages on the debian-user-digest list? I don't quite understand how 
the emails are put together. The email in the inbox contains attachments 
that are emails. Those email attachements I can open, but then those 
emails also contain more attached emails and those I can't open. I can't 
seem to hit the reply button to any of it.
