a few remarks:

      8  tmp=$tag.$RANDOM.tmp                                                          
      9  good=$tag.$RANDOM.good                                                        

i think mktemp(1) would be better here, because it assures unique file
names.

  # local spam.                                                                  
  (                                                                              
      cd 00-SPAM-MESSAGES/misc                                                   
      list=`/bin/ls -d [0-9]* | sort -n`                                         
      readmail 3 spam $list                                                      
  )                                                                              

you don't need the sorting here, do you?  your files even have leading
zeros in their names, so you might as well say:  "readmail 3 spam *"
and leave out the "list=..." part entirely.  if i got your setup
right, you might even be more precise saying "readmail 3 spam ???".

you don't have any european friends, right?  :) these rules would
catch non-ASCII from roman, european countries as well.  better than
this is a rule like:

  :0HB
  * 1^0 ^Subject:( *Adv:)|.*(±¤°í)|.*(±¤ °í)
  * 1^0 ^Content-Type:.*charset.*(euc-kr|big5|ks_c_5601-1987|ISO-2022-KR)
  $DEVNULL
