Privacy issue with comment notification emails

[atuttle]

When someone (not the blog owner) is subscribed to comments they get an email for each new comment that comes in. The FROM address for that email is the commenter's email address.

In general, blogs don't publish the email address of the commenter for privacy/spam reasons, but it is visible to the blog owner for contact/abuse/whatever reasons. This, then, would seem to be a bit of a breach of privacy.

Other popular blogs (Wordpress, Mango, etc) offer a configuration setting for the from address for comments, and it will often default to "comments@domain.com" or something like that.
