hey folks.. Im running the latest postfix on an ubuntu server with mailmain for mailing list management.. everything is pretty much working fine except that Im trying to get some kind of rate-limiting or throttling working for all outbound messages. Ive searched all over and found the smtpd -D and debugger_command = sleep 8 but for some reason, this doesnt seem to work for mails sent out via a mailing list with mailman.. I see emails getting relayed to my isp's smtp server one right after the other. Other settings I have been fooling with (in main.cf) are initial_destination_concurrency = 1 default_destination_recipient_limit = 1 default_destination_concurrency_limit = 1 smtp_destination_concurrency_limit = 1
I want only 1 smtp connection at a time to be made out from my server to my ISP's server.. Can someone please help me with a config that will accomplish this? regards, Jason
