Using the wrong terms adds to your confusion.
So you mean the email address (not host) isn't really relevant here and was not the source of the message being rejected? > Without the new log entry, we have no way of telling why it was > still rejected. Are you referring to the postfix entry from the successful delivery? It looks like pretty much every other: Mar 12 15:28:39 mail02 postfix/postscreen[4477]: CONNECT from [64.68.76.15]:19735 to [64.111.222.27]:25 Mar 12 15:28:39 mail02 postfix/postscreen[4477]: WHITELISTED [64.68.76.15]:19735 Mar 12 15:28:39 mail02 postfix/smtpd[23998]: connect from unknown[64.68.76.15] It's then processed by amavisd and delivered normally. Thanks, Alex
