First identify if it is a base 64 header, then store the decoded header in
a variable. Finally, test the contents of the variable.  I have a recipe
that starts as follows:


# B Mime header extension in subject?
:0
* ^Subject:.*=\?.*\?b\?\/.+\?=
{
  ## LOG="B mime header $MATCH $NL"
  MIMESUBJECT=`echo $MATCH | mimencode -u -b`
  ## LOG="B mime header $MIMESUBJECT $NL"

  # 5% gagabuggee subject
  :0 D
  * -1^1 MIMESUBJECT ?? .
  *  2^1 MIMESUBJECT ?? =[0-9A-F][0-9A-F]



You would need to put in a condition to check the iso-8859-1.  I have a
recipe that does something similar:

# Mime header extension in subject
:0
* ^Subject: =\?(gb2312|big5|ks_c_5601|2022-kr|euc-kr).*\?=
{



So adding them together, you get a recipe:

:0
* ^Subject:.*=\?.*\?b\?\/.+\?=
* ^Subject: =\?iso-8859-1.*\?=
{
  MIMESUBJECT=`echo $MATCH | mimencode -u -b`

  :0
  * MIMESUBJECT ?? ^Subject:.*Milhões pra cáça
  /dev/null
}

Note that that recipe is untested.
