Outgoing failures
Hi,
I have been using JES messaging server 6.2-3.04 (built Jul 15, 2005) as our corporate email server for a while without any problem. However, I have recently started getting the following postmaster reports for a specific domain for our outgoing email messages:
Temporary error from SMTP partner: smtp;421 abc.com SMTP incoming data timeout - closing connection.
Although it says temporary, it never succeeds to send, and eventually fails.
Any idea what might have gone wrong?
Thanks,

Hm. You seem to be talking about two differnet things.
Your error message comes from an external server, sending you data. That data stream stopped, and eventually timed out. Not much you can do about another system.
"it never succeeds to send"? What never succeeds? Are you talking about your system sending failing? Or that this external system can never send you anything?

Sorry for the misunderstanding. I checked with our users. They said that they were able to receive messages from that specific domain. But, their outgoing messages to that domain from our messaging server never get through. Briefly, in terms of our messaging server, we are able to receive from that specific domain, but we cannot send to them.
I got the following from the postmaster report of our messaging server about a failed outgoing message sent to that domain.
Delivery attempt history for your mail:
Sat, 21 Oct 2006 20:51:49 -0700 (PDT)
Temporary error from SMTP partner: smtp;421 abc.com SMTP incoming data timeout - closing connection.
Again, this report comes from our messaging server on a failed outbound message from us to a specific domain. I assume that this is the error message produced by the other mail server since it says "incoming data timeout".

Hi Rami,
From the message you provided it does indeed appear that the abc.com mail-server is timing out attempting to process the data you have provided. Assuming you haven't changed anything recently this could be due to a number of reasons including:
-> networking issues, the data is taking too long to be transferred (does this problem happen for small emails e.g. < 1KB)
-> processing issues at the other end (e.g. spamfiltering/virusfiltering at the other end takes too long).
-> changes at their end (e.g. timeout changes)
To troubleshoot this issue, you will need to get in contact with the postmaster of the other server and see if they can work out why the messages are rejected. You may also want to get a snoop of the outgoing traffic to see at just what point the rejection occurs. That may help determine where the problem lays e.g. during the data send.
Regards,
Shane.
