If you want the ability to email reminders, such as the Overdue Items Notice, to your patrons or staff you will need to configure how Alexandria communicates with your library's email server. Alexandria's email system is designed to potentially cope with hundreds of emails being sent (or resent) over many machines at the same time. If a send fails, the next resend time is generated by adding a random value between 3 and 9 minutes, spreading out the resend times so all the undelivered email still in the “short range” period isn't sent at the same time. If a send hasn't succeeded by the end of the “short range” period, the program will generate new send times using random values between 60 and 90 minutes. If a send still hasn't succeeded after 100 hours the email is discarded and a “return-to-sender” email will be sent. |
