Sometimes, new users reply to email2 Invitation or Notification Messages, which are sent using basic e-mail. When this happens, the reply is not sent securely via email2 as intended.

Most users that are replying to email2 Notification Messages are unaware that they are doing so. For this reason, when a user replies to an email2 Invitation Message, the initial sender's email address is automatically changed to a default 'do not reply' e-mail address such as 'email2-notification-do-not-reply@email2-pen.com' or similar depending where your PEN is hosted.

When an email2 message is sent to the default 'do not reply' e-mail addres, the email2 system will automatically notify the recipient back with a generic message that their reply did not make it to the intended recipients.

If a user is intent on replying to an email2 Invitation or Notification message, he or she may do so by changing the "email2-notification-do-not-reply@email2.com" e-mail address back to the initial sender's e-mail address. The purpose of this safeguard is only to prevent accidental replies, not intentional ones.
