I have an issue with email sending speeds on postfix. the email to yahoo are
getting throttled and getting suspended temporarily. I edited the main.cf
configuration to slower down the speeds and add a delay. This works fine
with email sending at delay but i have a problem here. the mails which are
there in deferred or retry queue, when they are sent, they are sent a very
high speed and throttles the connection. is there a way to control deferred
queue speed on postfix.

Error

relay=none, delay=419785, delays=419759/25/0/0.2, dsn=4.4.2, status=deferred
(delivery temporarily suspended: lost connection with
mta5.am0.yahoodns.net[67.195.229.58] while sending RCPT TO)

aol_destination_rate_delay = 250s
smtp_extra_recipient_limit = 10
yahoo_destination_concurrency_limit = 2
aol_destination_concurrency_limit = 2
transport_maps = hash:/etc/postfix/transport

Transport file

yahoo.com  yahoo:
aol.com   aol:


master.cf
yahoo     unix  -       -       n       -       -       smtp
aol     unix  -       -       n       -       -       smtp

How do i control speeds for deferred queue.

Basically i have the problems for all yahoo hosted mx records. Any help
would be appeciated.
