Hi,
This email contains several questions and all related my upgrade on Debian 6 of Postfix from version 2.7 to 2.9.3 (and for Debian this is 2.9.3-2.1~bpo60+1) I pipe email to dovecot via SA for content scanning and delivery, and had this option added , dovecot_destination_recipient_limit=1 This should make sure delivery of recipients is done one at a time. My server lacks memory and CPU. policy_time_limit=3600s I use this to keep SPF perl module from dying and restarting too often and I recall I had problems with this set at the defaults because SPF policy would not start again. My hack was to increase the policy time because there is always one email withing 3600 seconds, and not 1200 seconds. I have this in my master.cf: policy-spf unix - n n - - spawn user=nobody argv=/usr/sbin/postfix-policyd-spf-perl I would like to know what replaced these commands, and if they weren't replaced, then what changed within postfix that ensured I don't need to use them anymore, because I have this warning: postconf: warning: /etc/postfix/main.cf: unused parameter: dovecot_destination_recipient_limit=1 postconf: warning: /etc/postfix/main.cf: unused parameter: policy_time_limit=3600s Finally, I tried to turn of chroot in the master.cf and postfix would not start: postfix/master[28375]: fatal: /etc/postfix/master.cf: line 13: field "chroot": bad value: "no" I put this back a hyphen and postfix works! Thanks lots in advance if someone could shed a little light over here. Si.
