Use mime mail for all messages

I ran into some trouble when I tried to the the Job Posting module (http://drupal.org/project/job_posting) with my MimeMail configuration. When I had the "Use mime mail for all messages" box checked, whenever someone applied to a particular job posting, the email that the admin would receive would have no attachment (the resume should normally be attached) and the body of the email would be a bunch of craziness. (I have copied this text to a notepad doc and have attached it for your review.) I wasn't sure who needed to know about this, or if this was something that normally happens and I just dont fully understand. Just wanted to let you know.
