Postfix: slow transport?
I want to set postfix to use a "slow" transport for a particular site, because this site has limited a low rate for mail delivery, I did this:
Code:
# vi /etc/postfix/master.cf But I still been rejected by that site from about 14:00 to about 20:00 every day(The busy moment of a day): 554 sender is reject: 0, mx4, ...(in reply to MAIL FROM command) Before, when I didn't set default_process_limit=16, I got "IP is rejected" or "IP is hungup" from the mail server of that site and the mails were deferred. So I limit the process number, at first it's OK because there are many deferred mails in the queue, but now, after the deferred mails all have been delivered, some mails are bounced(in the time mentioned below), so I want to use slow transport, but it seems that there is no effect. why? Does the slow transport setting take effect? How can I know? how can I make sure the mails to XXX@163.com does only use the very "slow" transport--I haven't found "slow" word from maillog? Some other parameters I have changed: Code:
initial_destination_concurrency = 1 |
