Multiple recipient livecycle form using javascript in it to attach a pdf, external recipients get MIME formatted email.

Question

The livecycle designed form has javascript to send the form to 4 recipients.  The form worked fine until the mail domain was hosted by gmail (uses TLS, port 587).  Now recipients get a MIME email, not the attached PDF.  Old versions of the form pre-sept 29 work fine.  If we change the form or copy it, it does not work.  If we use a different smtp server to test, it works fine, all 4 recipients get the pdf.  Any advice is much appreciated!  I'd say gmail is the problem, but then why do old forms work fine still through gmail?
the setup is Adobe Livecycle Designer ES4, Adobe Acrobat XI, Outlook 2007, gmail hosted company domain (ex. yourdomain.com), using SMTP port 587 TLS, javascript in the email to declare a PDF, and a button to run the javascript (not a submit button, the javascript does the submit action).
problem looks like this:

Answer 1

First of all, a drop-down menu doesn't allow for multiple item selection. You'll need a list-box field for that.
Once you have that set up you can use the value(s) selected in this field as the recipients of the email.
