Why do emails sent by Constituents have my organization's email as the "From" email?

Improvements were made to the sending of emails on behalf of constituents in order to reduce the likelihood that they will be caught by spam filters. Previously, these emails had the constituent's address in the "From" field of the messages, which made them look like potentially "forged" (i.e., spam) emails. Now, the organization's email address is used along with the constituent's name. For example, "From: John Doe <website@your_organization.org>". The "Reply To" field still contains the constituent's address so replies will still go to the constituent. For example, "Reply-To: John Doe <johndoe@aol.com>".

The affected types of emails include Tell-a-Friend, TeamRaiser messages, Advocacy Action Alerts, eCards and Club emails.
