If you are using the mail/notification functionality in LiveCycle 7, you may find that the mails are never received by the intended recipient. If you look in the adminui you may find the action has stalled with the following error:
"javax.mail.MessagingException: 554 Mail from <email@example.com> rejected for policy reasons"
This is caused by a lack of privileges to use the SMTP mail server in your organisation.
Consult your IT department and request permission for the Lc Server to use the SMTP mail server to send email notifications.
