Subscribe by Email – domain mapping issue

The subscribe by email plugin is losing the URL for mapped domains (We are using WPMUDev Domain Mapping Plugin as well).

When the subscription email notifications go out for new posts on domain mapped blogs, the URL of the new post in the email is NOT the domain mapped version. It’s the original mysite.blognetwork.com. This looks bad and has generated several complaints from our customers already, as to why their URL is showing up incorrectly for their subscribers.

Is this a bug or a setting that we need to configure?

Thanks,

Jennifer
