I searched howto's & faq from postfix.org website. Hopefully the problem will be solved from this solution below. ---- 58. Help! I'm definitely an open relay. I've been listed with various black lists and everything. I'm sure my Postfix configuration is correct. What could be causing my system to relay?
If you have a gateway machine like a firewall, router, or another mail system between the Internet and your Postfix system, the combination might be causing your network to relay mail freely. If the gateway system's IP address is in your mynetworks parameter, and it's configured to pass all mail to your Postfix system, it has carte blanche to relay anything. Removing the gateway system from your mynetworks parameter should fix it. ---- We have /etc/postsfix/mynetworks configured. I specified the IP (for e.g. 192.168.0.1) only instead of network/netmask patterns (e.g. 192.168.0.0/24), because our postfix server is connected to an aDSL router/gateway. QUESTIONS: 1. In /etc/postfix/mynetworks, can I configure the IP only (e.g. 192.168.0.1) instead of network/netmask patterns configuration? I worrying kasi the windows clients might not be able to send e-mails if the IP only is specified. 2. Also after reconfiguring /etc/postfix/mynetworks, the maillog below is appearring: Aug 14 15:50:44 mail postfix/smtpd[14580]: NOQUEUE: reject: RCPT from www.ecotriangle.com.ph[203.160.186.69]: 554 <[EMAIL PROTECTED]>: Relay access denied; from=<[EMAIL PROTECTED]> to=<[EMAIL PROTECTED]> proto=SMTP helo=<doramail-com-bk.mr.outblaze.com> Aug 14 15:50:45 mail postfix/smtpd[14580]: NOQUEUE: reject: RCPT from www.ecotriangle.com.ph[203.160.186.69]: 554 <[EMAIL PROTECTED]>: Relay access denied; from=<[EMAIL PROTECTED]> to=<[EMAIL PROTECTED]> proto=SMTP helo=<doramail-com-bk.mr.outblaze.com> Do I need to worry about these maillog errors? The previous problem in my observation (from maillogs) is solved already. hopefully the problem is really fixed already.
