With Postfix 2.7 and later use a per-sender FILTER action without
next-hop destination:
[email protected] FILTER sender-class-1:
In master.cf specify a sender-class-1 SMTP client.
sender-class-1 unix - - n - - smtp
In main.cf specify sender-class-1_destination_rate_delay=1 to limit
the per-sender rate to one message per second.
