I need to delay sending the email.
I add string
smtp_transport_rate_delay = 1s
to /etc/postfix/
but I didn't see a delay...

this seting is only applied beteween messages
The default amount of delay that is inserted between individual message deliveries over the same message delivery transport, regardless of destination. Specify a non-zero value to rate-limit those message deliveries to at most one per $default_transport_rate_delay.

also to edit the you have to adapt the templates instead of editing directly:
I have to add default transport rate delay = 1s in /var/lib/pmg/templates/ ?
