Error while trying to send mail to user - intermediate channel settings

Question

Hi,
I am trying to implement the intermediate_channel code program, and for that I have made changes to my configuration file as follows.:-
if you search for the phrase '" ADDED", it will take you to all those places where I have made entries.
! IMTA configuration file
! part I : rewrite rules
! Domain Rewrite Rules.
! Uncomment this line to use domain rewrite rules
! from the configuration file instead of the domain database.
! Please refer to the iMS documentation for details.

imsimta version shows:-
Sun Java(tm) System Messaging Server 6.1 (built Apr 28 2004)
libimta.so 6.1 (built 13:10:36, Apr 28 2004)
Question is: when I try to send a mail to the user as
[email protected], it gives an error.
I am trying to send a mail from another of my linux machines as
telnet mahandi.startcom.com 25
at
rcpt to: [email protected], it throws the error:
550 5.1.2 unknown host or domain: [email protected]
What could be the possible reason for this.
thanks ,
Sandeep.

Answer 1

I think I should first tell you what we want to do:-
For each message that comes in:-
1) we want it to be sent to our program
2) from our program we want to call our application that will go through the message, and on the basis of certain rules built into the application, will decide whether the message needs to be re-enqueued or discarded.
For the above I need to certain configurations.
I think I can use the intermediate_channel.c program that comes with the SDK in the /example/mtasdk directory, and from that program can call the application.
Please suggest on the above.
Coming to my present configurations.
No, I had not added the xloop_test channel to the job_controller.cnf file.
However, I had added the channel to the job_controller.site file as:-
[CHANNEL=xloop_test]
master_command=/opt/SUNWmsgsr/examples/mtasdk/intermediate_channel
(where intermediate_channel is the compiled version of the intermediate_channel.c pogram that comes with the SDK examples.)
Now, I have done something else:-
First, in the imta.cnf file, I have removed the
above 2 lines from the part I : rewrite rules, keeping the part 2 same and I added the following line:
$* $U%$D@x-looptest-daemon$Nxloop_test
I have added the following 2 lines to the job_controller.cnf file.
[CHANNEL=xloop_test]
slave_command=/opt/SUNWmsgsr/examples/mtasdk/intermediate_channel
With this configuration, my message is going to my yahoo account, and the mail.log_current file is showing the enqueue and deque, however, my intermediate_channel program is not being invoked.
This is where I am getting confused now.
thanks.
