[Koha] Overdue reminder emails in Koha

[Chris Brown]

Hello,

Is there any way to configure Koha to send out a reminder email a couple of
days BEFORE a book is due back? For example, can I enter a negative number
in the "Delay" field on the overdue notice / status triggers screen?

Also is there a log kept of the overdue notices that have been sent?

I am using Postfix to send mail, and Koha 17.11

Thanks,

Chris Brown
