No, but you can control the delay between successive deliveries. http://www.postfix.org/postconf.5.html#transport_destination_rate_delay http://www.postfix.org/postconf.5.html#default_destination_rate_delay Caution: the resulting behavior depends on the value of the corresponding per-destination recipient limit. If you set the per-destination recipient limit equal to 1, you will send too much email. - With a corresponding per-destination recipient limit > 1, the rate delay specifies the time between deliveries to the same domain. Different domains are delivered in parallel, subject to the process limits specified in master.cf. - With a corresponding per-destination recipient limit equal to 1, the rate delay specifies the time between deliveries to the same recipient. Different recipients are delivered in parallel, subject to the process limits specified in master.cf. Wietse
Re: Yahoo blocking emails from Postfix
Thanks Yeah, i know it does not depend on the MTA. I use multiple IPs with SPF, DKIM and DMARC. Regularly update the lists, used transport to limit yahoo sending but no success. The problem i see that even though set a delay to send to yahoo, the emails which are there in deferred queue tend to flush really quick and the IP gets grey listed again. Anything you suggest to control the sending speed and the retry interval at which deferred queue gets flushed out. Can we control the amount of emails which gets from deferred queue to active queue. -- Sent from: http://postfix.1071664.n5.nabble.com/Postfix-Users-f2.html

Not that I have noticed, not for many years. I suppose IP reputation has a lot to do with it, and also that any site sending marketing mail should sign up for feedback loops with large receivers such as Yahoo. There are more unknown variables here that inhibit useful comment. One thing I'd like to point out, however, is that the emails aren't "from Postfix", and that the blocking has little or nothing to do with the choice of MTA. Yes, some of the workarounds for poor or nonexistent IP reputation include various transport(5) hacks, but ultimately to address the problem, the answer lies outside of Postfix. I'd recommend: - strict list hygiene - sign up at dnswl.org - if money depends on deliveries, spend some on a good ESP -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:

Yahoo blocking emails from Postfix
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) smtp_destination_concurrency_limit = 3 smtp_destination_recipient_limit = 5 data_directory=/var/lib/postfix multi_instance_name = postfix multi_instance_enable = yes yahoo_destination_rate_delay = 300s 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. -- Sent from: http://postfix.1071664.n5.nabble.com/Postfix-Users-f2.html
