Hello Everyone.
Our company sends out newsletters to people who have subscribed their mail address in-store (retail). I have been working in attempt to slow down E-Mail deliveries to Hotmail, as our server attempts deliveries too quickly and will get blocked by their servers. I have googled and found some decent information and have even applied it, but it does not appear to do a single thing to slow delivery down for the domain. I have in my configuration files: Master.cf: smtphotmail unix - - - - 3 smtp Transport: hotmail.com smtphotmail:hotmail.com Main.cf: smtphotmail_destination_concurrency_limit = 2 smtphotmail_destination_rate_delay = 3s I was using the global limiters and these were working just fine - we were able to deliver OK, until I commented them out: #initial_destination_concurrency = 3 #local_destination_concurrency_limit = 3 #smtp_destination_concurrency_limit = 3 #smtp_destination_rate_delay = 2s It appears that whenever I use the smtphotmail transport rules, instead of the global ones, delivery attempts to the domain increase as if there was no limitation.. Ie: after a Postfix reload, I follow the mail.info log and find straight after the reload that there are instantly pages and pages of delivery attempts to hotmail.com. To me this doesn't make sense - the rate limit means I should only see a few, every couple of seconds, right? Am I missing something here? Thanks in advance, Yours Sincerely, Michael Hutchinson
