InfoPath 2010 - send custom email with form data attachment

Question

I am trying to submit a Web Browser Form to a document library in another web application which has incoming email enabled. So far I have identified two problems with this:

1. SharePoint 2010 doesn't allow email messages with the X-Mailer value including "SharePoint" (this value is set by InfoPath/SharePoint) to be imported.
2. SharePoint apparently doesn't allow the email message content-type (mime type) "multipart/related" to be imported.

I've tried getting around this with VBScript in the form of smtpreg and an additional "OnArrival" filter that removes the X-Mailer header. However, changing the content type is either really difficult or impossible using the VBScript method.

People talk about sending emails using the FormCode of an InfoPath form, but I am not seeing how to send an email using System.Net.Mail and still include the form data as an attachment, like the normal email submit. My guess is that if I send the attachment using System.Net.Mail I can either set the mime type for the email message manually, or it will default to multipart/mixed instead of multipart/related.

How can I make this happen or is it even possible? I am open to solutions that involve either the VBScript approach or the FormCode/CodeBehind approach for InfoPath.

Answer 1

In the end this doesn't seem like a viable solution without high levels of customization. I ended up changing directions and going with the Form Code option and just elevating the permissions and submitting directly to the Library instead of messing around with all this email stuff. The results are similar to having the email solution working and they are about equally likely to be abused.
