SMTP delay

[goro22]

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

Why?

 

[dcsapak]

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.

see https://www.postfix.org/postconf.5.html

also to edit the main.cf you have to adapt the templates instead of editing directly:

I have to add default transport rate delay = 1s in /var/lib/pmg/templates/main.cf.in ?

I did this in my cluster but it erased on secondary nodes
