Hi,

Is any one faced problem like Connection attempt failed, status = ECONNREFUSED.
We are facing this problem when sending mail to particular domain.

PMTA Error Log:
Connection attempt failed, status = ECONNREFUSED while connecting from m1.emailserver.com (0.0.0.0) to acsinet11.oracle.com (141.146.126.233)

Is our connection is refused in oracle server side?  how can we solve this problem?

There lot domain's are in queues. Is this affects any delay in other mail delivery ?

Thanks,
Ramesh

Hello Rames,

Try this and see the result:

Code: [Select]

pmta resolve --connect --source=m1.emailserver.com,0.0.0.0 acsinet11.oracle.com

Hello,

It seems your connection to that server is being refused. Here is what I see:

If you are running PowerMTA v4.0, the trace command output now shows up on the screen by default vs. in the log file, making it easier to see firsthand the SMTP transaction and result.  Also with v4.0, you can run commands from within the monitoring facility vs. at the command line if you do not have access to the command line. 

If you are using the new PowerMTA Management Console, you can also run the trace command (and others) from the "Commands" page or right from within the queue that is being monitored (see the Actions" tab on the queue details page).  Again, the output shows up right on the screen vs. in the log file be default.

Another site recently mentioned being blocked by Oracle, and they sent an email to postmaster@oracle.com to help resolve the issue (at least to help find out why they were blocked), so we would suggest trying this as well, and of course then complying with their policies (which you should inquire about).
