Problem with daily activity digest email "from" address

The from address on daily email digests is not showing the site name. Instead, it shows my name @ my ISPs address. I saw what appeared to be a sImilar problem listed with mimemail. The solution for that user was to update mimemail to the latest dev version. That didn't solve this problem for me.

If it makes a difference, I am using Commons Origin.

Any ideas where activities digest might be pulling this email address from? It isn't somethingnI would have set anywhere.

Thanks.
