[T-Mobile Samsung Galaxy S 4] Adam0524:
While not impossible, it would be a little tricky and alot of work

Here is the current xml for notifications from mail droid

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:orientation="vertical" android:padding="10.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content">
<ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/notification_airplane" />
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>

See how it only has 1 entry for notifications and doesnt define any email providers.

Youd have to rewrite the entire thing and figure out how to make it know which email is getting the notification and which icon to display. Then after you spent a while figuring that out youd have to track down every xml that uses this xml and edit appropriately to know whats it use from this xml in the event of a notification from a specific email provider.

and on top of that heres all the providers mail droid supports
