[Koha] Claim is not sending a serial claim notification

[Manju N]

I am using koha 3.6 and postfix mail in which claim email notice is not
generating for serial claim  but other notification for patrons are working
fine.

I can view claim log activity Under Tools-Additional tools-Log viewer
information but not sending claim notices to respective vendor email id.

Can anyone suggest me  how to fix this ?
