I have deployed a postfix(2.6.6) server for email receiving. On this I have configured SenderID + SPF milter, by referring to

The command that I used is as follows:

./sid-filter -u postfix -p inet:10027@localhost -l

Following are my settings in file:

#Milter support for smtpd mail
smtpd_milters =

# Milters for non-SMTP mail.
non_smtpd_milters =

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:

connect from[]

May 25 13:20:02 g2xxxxxg postfix/smtpd[11733]: C11F9B0194:[]

May 25 13:20:03 gxxxxxg postfix/cleanup[11814]: C11F9B0194:

May 25 13:20:03 gxxxxxg postfix/cleanup[11814]: C11F9B0194: milter-reject: END-OF-MESSAGE from[]: 5.7.1 Command rejected; proto=ESMTP

Here the 'sid-filter' is giving problems.

Any idea, what I am doing wrong?

Please help.

Thanks in advance

Problem solved.

I had to relaunch the sid filter with following command:

./sid-filter -u postfix -p inet:10027@localhost -l -L 8

This resulted in finest log being generated and that convinced me that sid-filter was working correct.

Actually it was the network environment that was not setup properly and resulting in problems.

Thanks to all of those who looked on the problem.
