[Koha] Email notification in koha

[amit bondwal]

Hi,

I want to enable email notification for everything happen for patron in
koha like new patron added,
checkout, checkin, overdue notices etc.

I am able to set email notification for new patron created, it send
username and password to
the user's email id but rest of the notification like checkin and checkout
not working it showing
pending message in patron account.

Thanks and regards.
