$body returns: MIME::Body::InCore=HASH(0x83a39ac) while $filename comes out blank.

Update

  foreach $x (@attypes){
    if ($subentity->mime_type =~ m/$x/i){
      $attachment = $subentity->bodyhandle->print();
      push @attachment, $attachment;
      print "x = $x subentity =".$subentity->mime_type."\n";
      push @attname, $subentity->head->mime_attr('content-disposition.
+filename');
     } 
  }

The attachment prints out but is not stored in $attachment. @attname now holds the attachment name correctly. All that remains is figuring out how to store the attachement into a variable for later use.

You're setting $attachment to the return value of the print() method. The perldoc for MIME:Body doesn't say anything about print() returning anything. There are other methods that look like they'll do what you want, like as_string() and as_lines().

MIME::Tools has some of the better documentation I've seen for modules, with lots of examples. You should run "perldoc MIME::Body" or look at these pages on perldoc.com:
http://www.perldoc.com/cpan/MIME-tools.html

program < single.message.mime

Update: './mimemail' directory should already exist. Also removed unneeded 'my $msg_body;' line.
