Submit InfoPath Form as System Admin instead of System Account

Hi,

I have an InfoPath 2010 form which will be accessed anonymously.  When submitted, it will save to a document library.  In order for an anonymous user to be able to submit the form (to the library), I must use code behind to run with elevated privileges.  This is all fine and it works except it submits it as System Account.  

This is a problem because I need to create a workflow that will send an email to a group mailbox (can’t do this through an alert), and workflows do not trigger when an item is added from System Account.  I’ve looked everywhere and tried everything to get the code to submit as the System Administrator account instead using the UserToken but I have not been successful.  I thought about creating an event receiver, but I don’t want the hassle of managing one for each form that may eventually need this same functionality.

Here is my code behind:

This works but submits as System Account:

public void btnSubmit_Clicked(object sender, ClickedEventArgs e)
{
     // Write your code here.

    SPSecurity.RunWithElevatedPrivileges(delegate()
    {
        this.Submit();
    }
}

After doing a bunch of reading, I tried this with no luck.  It submits as System Account as well:

public void btnSubmit_Clicked(object sender, ClickedEventArgs e)
{
// Write your code here.

SPWeb webInUserContext = SPContext.Current.Web;
SPSite SiteInUserContext = SPContext.Current.Site;
Guid webGuid = webInUserContext.ID;
Guid siteGuid = SiteInUserContext.ID;

SPSecurity.RunWithElevatedPrivileges(delegate()
{
//Get Web and Site impersonated as SHAREPOINT\System
using (SPSite site = new SPSite(siteGuid))
{
using (SPWeb web = site.OpenWeb(webGuid))
{
//right now, logged in as SHAREPOINT\System Account
//impersonate site admin account and continue
SPUserToken userToken = GetSystemToken(site);
using (SPSite impersonatedSite = new SPSite(siteGuid, userToken))
{
using (SPWeb impersonatedWeb = impersonatedSite.OpenWeb(webGuid))
{
impersonatedWeb.AllowUnsafeUpdates = true;

//NOT SURE WHAT TO DO HERE.

//this.Submit(); works but only submits as System Account

impersonatedWeb.AllowUnsafeUpdates = false;
impersonatedWeb.Dispose();
}
}
web.Dispose();
}
}
});
}

public static SPUserToken GetSystemToken(SPSite site)
{
site.CatchAccessDeniedException = false;

SPUserToken sysToken = null;

SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite siteWithElevatedPrivileges = new SPSite(site.ID))
{
sysToken = siteWithElevatedPrivileges.RootWeb.SiteAdministrators[0].UserToken;
}
});
return sysToken;
}

Any advice would be greatly appreciated.  I’ve attached a file too for ease of reading.
