Wietse,
Show actual evidence: two complete logfile records that are too close
together.
My original email showed those two records. Aren't they what you're asking for?
And also, show evidence that you haven't made the mistake of setting
xxx_destination_recipient_limit=1 (where xxx is the mail delivery
transport that talks to google etc.).
master.cf:
slow unix - - n - 1 smtp
-o syslog_name=smtp-slow
main.cf:
transport_maps = hash:/etc/postfix/transport
default_destination_rate_delay = 12
default_destination_concurrency_limit = 1
default_destination_recipient_limit = 5
slow_initial_destination_concurrency = 1
slow_destination_concurrency_limit = 1
slow_destination_recipient_limit = 5
slow_destination_rate_delay = 12s

Thank you.
