If I understood the release notes correctly, with "smtpd_proxy_options = speed_adjust", each smtpd process will keep the message it's currently receiving in a temporary file. That seems to imply that there could be
(number of smtpd processes) * message_size_limit bytes of queue space allocated in temporary files. I _think_ that this is not different from a setup without a content filter which would mean I don't have to increase the disk partition keeping the queue - is that assumption correct? Stefan
