ops.. my bad
I suspect you have to create a custom template also for these files:
./etc/e-smith/templates/var/service/qpsmtpd/config/plugins/13bcc
./etc/e-smith/templates/var/service/qpsmtpd/config/peers/local/13bcc
repeat the steps above modifying the folders accordingly
when done, raise
signal-event email-update
let us know, thank you
if something goes wrong, simply delete the templates-custom/var/service/qpsmtpd/config/ folder and raise the email-update event
