This control lets you specify the address that is used as the From and
Reply-to addresses for email digests sent by Traction. It must be specified.
You can enter just an email address, e.g. cjn@tractionsoftware.com,
or you can enter both an address and a name, as shown above.
This person is also referred to as the Mail
Digest Administrator because email replies, bounce messages,
and out-of-office notifications triggered by the digest will be directed
to this email address.
