Hi Stefano, and thank you for responding.
"10.1.1.17" is my own workstation (laptop), and reference to it seems to
indicate that it was the origin of the bouncing message.
"srv3.office.chemitech.ru" is the JAMES server.
My workstation platform is Vista.
"ping james.apache.org" and "ping james.apache.org." from my laptop both
succeed without any trouble. The same is from the JAMES server itself. But I
did not make any systematic tests if this availability or name resolving are
stable enough.
My JAMES is configured as "smart host" that has a special delivery channel
to the neighboring server for "chemitech.ru", but I do not expect this to
influence delivery to the apache.org domain...
Any more ideas are most welcome...
My best regards,
Sergey

Subject: Re: 3.0-M3-SNAPSHOT - strange bounces of outgoing mail
2011/4/18 USHAKOV, Sergey <[email protected]>:
Hi all,
while running JAMES in semi-production mode and using it as an outbound
SMTP
server, I occasionally get strange bounces like the one quoted below. A
second or third attempt to send out the same mail usually succeeds.
The first line suggests that it may be some DNS problem. My shallow guess
is
that it may be due to a local DNS server failure to respond in timely
manner.
If yes, are there any settings that might allow for longer timeouts on DNS
requests?
My "dnsservice.xml" looks nothing fancy, but is also appended below, to be
on the safe side...
"550 rejected: Unknown recipient" is an SMTP error received from the
remote server (10.1.1.17).
The bounce has been created by "srv3.office.chemitech.ru" while
talking to "10.1.1.17".
Now you should try to understand why srv3.office.chemitech.ru was
talking to 10.1.1.17 in order to deliver a mail for @james.apache.org:
- Are you using a gateway in remote delivery?
- what OS do you run?
- Can you try a "ping james.apache.org" from that machine? and "ping
james.apache.org." (note it ends with a dot)?
- If you're on linux can you paste the content of /etc/resolv.conf and
/etc/hosts ?
- Is "srv3.office.chemitech.ru" the james server?
- What is 10.1.1.17 ?
Stefano
Thanks and best regards,
Sergey
