I just tried that and it worked with no problem. I also just tried
formail -ds <oldmailfile >>newmailfile  which will "convert a 
non-standard mailbox file into a standard mailbox file." The input and 
output boxes aren't quite the same size, the new one is 95 bytes bigger 
than the old but squirrelmail can't access it either. I also tried 
formail -s to resend my entire mail file to the test account with the 
same result, squirrelmail won't show the mail. It's interesting that the 
new mail file is 64355357 bytes and the old file is 64002417 bytes, 350K 
bigger for the new.
