Hi,
I have a fedora20 server with postfix-2.10.5 I'm trying to configure
rate limiting for outbound mail to google, yahoo, etc, in hopes of not
only building a better reputation with these systems, but also to
prevent my outbound pipe from being saturated.
I've configured a few of the rate_delay parameters according to the
instructions here:
http://steam.io/2013/04/01/postfix-rate-limiting/
It includes building two new transports in master.cf
polite unix - - n - - smtp
turtle unix - - n - - smtp
And in /etc/postfix/transport
gmail.com polite:
yahoo.com turtle:
hotmail.com polite:
In main.cf I've configured:
transport_maps = hash:/etc/postfix/transport
polite_destination_concurrency_limit = 10
polite_destination_rate_delay = 0
polite_destination_recipient_limit = 5
turtle_destination_concurrency_limit = 5
turtle_destination_rate_delay = 3s
turtle_destination_recipient_limit = 2
I believe the problem is that messages not destined for gmail, yahoo, or
hotmail no longer have a path, correct?
Do those rates and delays look okay?

Any ideas greatly appreciated.
Thanks,
Alex
