Hi, I have deployed a postfix server for email receiving. On this I have configured DKIM and SenderID + SPF milters, by referring to http://www.postfix.org/MILTER_README.html
Following are my settings in main.cf file: #Milter support for smtpd mail smtpd_milters = inet:localhost:10026, inet:localhost:10027 inet:localhost:10028 # Milters for non-SMTP mail. non_smtpd_milters = inet:localhost:10026, inet:localhost:10027 inet:localhost:10028 milter_default_action = reject # Postfix . 2.6 #milter_protocol = 6 # 2.3 . Postfix . 2.5 milter_protocol = 2 Now I have this observation: 1. One of the postfix that is setup on AWS CentOS 5.5 is working fine and is able to receive mails on defined mx record. 2. One of the similar postfix(as in step 1) that is setup behind one of the corporate firewalls is not able to receive any mails and is giving following type of error logs: May 23 21:18:23 g2t0385g postfix/cleanup[14109]: F0CD6B0194: milter-reject: END-OF-MESSAGE from xxxxx444g.austin.hp.com[xx.xxx.xx.xxx]: 5.7.1 Command rejected; from=<ashiish.sha...@gmail.com> to=<536eji22ou...@xxx.com> proto=ESMTP helo=<mail-fx0-f45.google.com> Any idea, what I am doing wrong? Please help. Thanks Ashish Sharma
