$msg = MIME::Lite->new(
       From => 'net-admin@someplace.org',
       To   => 'decoraw@someplace.org',
       Subject => 'Trying to send attachment',
       Type => 'multipart/mixed');

BTW, the "Type" param is not needed in the call to new(). When calling $msg->attach later, the object will automatically set the Type as needed. See the docs for more details.

And I agree that MIME::Lite is definitely one of the coolest things since sliced bread. Major kudos to the author. I'm using it at work to mail out dynamically generated PDF's, and I think it took me all of 5 minutes after reading the docs to have working code. That's a well designed module. :-)
