Oh my what a mess! Funny read though ;-)
I'm not surprised I've been having problems. That in addition to corrupt 
messages, missing subjects, having been through multiple systems and 
apparently being a mix of several MBOX formats.
Well, having finally completed importing all those MBOX files into 
Mailman I hope I never have to do it again.

I used the Thunderbird email program to organize them while 
simultaneously editing problematic MBOX documents in a text editor.

Failing to remove them resulted in every message appearing in the 
current month and without a subject. Using the Grep command in my text 
editor to remove those lines put them where they should be (correct 
dates) and with their subject headers.
I also realized that I had to rename all occurances of lines in the body 
starting with "From" to "from" or else those messages would get all 
messed up (not showing their body contents at all or only partly showing).

I didn't try it, but I could probably have renamed all lines in the body 
from "From" to ">From". Oh well, at least it works now.

Thanks for the insight from you and others and especially for Mark 
Sapiro's help and patience on the subject!
