How can I be Certain My Email Messages Were Delivered?
Lyris maintains its outgoing mail queue in a database file called "outmail.dbf" If you own a database program, such as Microsoft Access, Paradox or FoxPro, or a program that can view
database files, such as Microsoft Excel, you can view the Lyris mail queue.
Next to each individual message is a record of whether an attempt was made to send the message. If there was, and the message was successfully delivered, the exact date and time of the delivery are
recorded. If the message was not successfully delivered, the exact error message (for example, "no such user") is recorded, along with the attempt number. Lyris will re-attempt to send undelivered
mail for three days. Each re-attempt will occur around 1am in the morning.
