I recently upgraded a 1.5.3 blog to WP 2.0.9. It went smoothly, and worked with the custom theme he'd been using.
However, comment notification emails now bear the web hosting account's default email address as the "from" address instead of the commenter's email address (which is how it worked prior to the upgrade).
One thing I note is that, although he vaguely remembers using the default hosting email address earlier, there is no longer a user called "admin" -- and the hosting email address is not in the database.
But that does not explain why the commenter's email address has been replaced by what *might* have been the admin address in comment notifications.
By the way, this is on a Bluehost web hosting account.
We've tried replacing a few files, but no joy. Does anyone have any words of wisdom for this?
This appears to be a WP 2.0.9 problem
I've tested our other 2.0.9 upgrades and they all exhibit the same behavior: comment notifications have some sort of default address (like firstname.lastname@example.org, even if it doesn't exist) in the "from" field, while the commenter's email address is in the body of the email, along with other data (IP address, URL and comment). Surely this is an ease-of-use a problem if people want to send a reply to the commenter?
