I had posted an awk script which was my first attempt at reformatting mboxes
and news mailbox-style files for the NeXT, but I just sat down and rewrote it
so that it works 98% of the time.  Just take any mbox that currently causes
Mail.app to barf (vax mboxes did, and so do all saved news mailboxes) and say

convert bad.mbox > good.mbox

save this script as "convert" (or whatever) and just run it as a shell script.

++++++++++++++++++++++++++++++++++++
$1 !~ /^Date:/ && $1 !~ /^From: /       { entry[line]=$0; line++;}
/^From: / {
	printf ("%s %s %s\n", "From", name, fromdate);
	print origfrom;
	print origdate;
	while(i < line-1) { print (entry[i]); i++;}
	i=0; line=0;
	printf ("\n\n\n\n");
	origfrom=$0;
	if ( $2 !~ /^[A-Za-z]/ ) name = substr($2,2,length($2));
	else name = $2;
	}
/^Date: / { origdate=$0;
	if ( $2 ~ /^[0-9]/ ) {
		if( length($7) == 0 ) $7="Sun";
		fromdate=sprintf("%s %s %s %s 19%s", $7, $3, $2, $5, $4) ;
	}
	else if ( $3 ~ /^[0-9]/ )
		fromdate=sprintf("%s %s %s %s 19%s", substr($2,0,length( $2)-1), $4, $3, $6, $5);
	else
		fromdate=sprintf("%s %s %s %s %s", $2, $3, $4, $5, $6);
	} 
' $1

This works much better than the old one!
