I configured remote systems postfix to relay email via my connection, the setting on all 3-systems are identical in postfix/main.cf
Once system is working correctly, relaying the mail via my "relayhost" Two other system giving me an error in log file: "External senders are prohibited to send to local recipients without authentication" Authentication is the same as on the first system that is working. Though, I notice that the first system mail.log file has: from=<r...@white-domain.com> The two other systems (that bounce the mail) have: from=<> Where is the setting for "from <>" I use command line to test the mail. -- Thelma
