I implemented postscreen quite a while ago. I don't see where or how it introduces a delay to force the originating MTA to queue and try later. That seems to be what is benefiting me. So far, there have not been any complaints of desired mail not being delivered. There were only 6 defers yesterday. Normally there are a couple hundred. -- Doug _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
