I'm not very good with procmail, but I know that procmail will allow you
to pass the input through a pipe, so you could set a filter that matches
all mails to pipe to perl. With that the perl "one-liner" is handy (-n
for treating the code as being inside while (<>)):
perl -ne "if ($_ =~ m/(=[0-9a-fA-F]{2})/) { $text = $1; $replace =
chr($text); $_ =~ s/$text/$replace/g; }
It's not perfect, but I think you understand where I'm going with this.
