Here are a concrete example of mine:

</etc/postfix/master.cf>
google     unix  -       -       -       -       -       smtp
    -o soft_bounce=yes

</etc/postfix/main.cf>
smtp_tls_policy_maps = hash:/etc/postfix/tls_policy
transport_maps = hash:/etc/postfix/transport
google_destination_concurrency_failed_cohort_limit = 100
google_destination_rate_delay = 3

</etc/postfix/transport>
gmail.com       google:
google.com      google:

</etc/postfix/tls_policy>
gmail.com       verify
google.com      verify


Above settings are a compromise with Google. Like Microsoft, Google also
imposes limits on the size of email transmissions per mail server
(outbound), as you know, thanks!


Sincerely, Byunghee
