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 which 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 in the middle of the night, around 1am in the morning.
