Please try to avoid using JIRA as a discussion tool. Use the mailing list(s) to
discuss potential problems.
The DEBUG level for the the smtphandler will log all of the protocol
requests/responses. It will not log the data, but will log other things. If
necessary, additional logging could be added in a private build to isolate where a
problem is happening in your reproducible environment.

If there is an exception during processing, James should not deliver the message. The
fact that it attempts delivery indicates that the code has entered processMail (beyond
processMailHeaders) without any prior Exception. What happens next is this:
- processMail creates a new MailImpl with an InputStream.
- MailImpl creates a MimeMessageInputStreamSource.
- MimeMessageInputStreamSource reads the entire InputStream
into a temporary file.
- The InputStream returns -1 when the <CRLF>.<CRLF> is found.
- MimeMessageInputStreamSource throws a MessagingException
if there is an IOException processing the InputStream.
If we get to the sendMail call in processMail, James believes that it has properly
received an entire message, whose contents would be temporarily located in a .m64 file
under $PHOENIX_HOME/temp/.

Here is an overview of the issue:
---------------------------------------------------------------------
Key: JAMES-282
Summary: Mail not correctly deliverd after DNS time-out on From: address
Type: Bug
Status: Unassigned
Priority: Major
Project: James
Components:
DNSServer
SMTPServer
Versions:
2.2.0RC2
2.2.0RC3
2.1.3
Assignee:
Reporter: Hes Siemelink
Created: Mon, 10 May 2004 6:46 AM
Updated: Wed, 12 May 2004 9:09 AM
Environment: Windows 2000
Description:
Some emails keep hanging in my sendmail queue. When they are delivered through James I
receive a crippled version (no subject, no body) and an error is sent back to Sendmail
that the message could not be delivered. The message keeps hanging in the queue and
blocks delivery of all messages that are behind it.
We can accurately reproduce the problem by filling in an address in the 'From' header
that can not be resolved by DNS.
This problem might by hard to reproduce and I apologise for the lengthy description
that follows. I don't know what's going on exactly but I think it would be best to
give you plenty of information.
I will try to give an accurate description of the situation.
The email I try to send is:
From: "Tom" <[EMAIL PROTECTED]>
To: "Hes Siemelink" <[EMAIL PROTECTED]>
Subject: TEST unkown From
Date: Tue, 2 Mar 2004 12:46:05 +0100
Message-ID: <[EMAIL PROTECTED]>
MIME-Version: 1.0
Content-Type: text/plain;
charset="us-ascii"
Content-Transfer-Encoding: 7bit
Hi Hes,
Thanks for the info.
Tom
The domain 'xxxxx.org' can not be found in the DNS:
[EMAIL PROTECTED] hes]$ dig xxxxx.org
; <<>> DiG 9.2.1 <<>> xxxxx.org
;; global options: printcmd
;; connection timed out; no servers could be reached
If I change the domain in the from address to [EMAIL PROTECTED], delivery is fine.
In a test run, the message is first sent to our Sendmail server. Sendmail attempts to
deliver it to the recipient '[EMAIL PROTECTED]'. Here is a transcript of what happens
then:
Forcing the attempted delivery of mail with the command /usr/lib/sendmail -v -q

[EMAIL PROTECTED] Deferred: Connection reset by extra3.izecom.com.
... etc ...
Note that the 123 messages are never delivered.
In the James logs I can see the delivery of the first message was succesful.
10/05/04 15:23:44 INFO smtpserver : Successfully spooled mail

(Mail1084195424201-17) sent successfully to 192.168.0.18 at 192.168.0.18
The James server in this case functions as a relay. Mail is delivered to an Exchange
server (running at 192.168.0.18). The (reconstructed) email that is received is:
Received: from izecom-martijn ([192.168.0.18]) by izecom-martijn.exchange.izecom.com
with Microsoft SMTPSVC(5.0.2195.6713);
Mon, 10 May 2004 15:23:44 +0200
Return-Path: <[EMAIL PROTECTED]>
Received: from 192.168.0.1 ([192.168.0.1])
by izecom-martijn (JAMES SMTP Server 2.2.0RC3) with SMTP ID 385
for <[EMAIL PROTECTED]>;
Mon, 10 May 2004 15:23:44 +0200 (CEST)
Date: Mon, 10 May 2004 15:23:44 +0200 (CEST)
From: [EMAIL PROTECTED]
Bcc:
Message-ID: <[EMAIL PROTECTED]>
X-OriginalArrivalTime: 10 May 2004 13:23:44.0295 (UTC) FILETIME=[0490F370:01C43692]
So... other points of interest:
* There is similar behavior with James 2.1.3. In stead of "Deferred" the SMTP
response of james is I/O error.
* The problem does not occur if I talk to directly to James. It is only in
combination with Sendmail.
* The problem does not occur id I talk to directly to Exchange.
* Mailets/Matchers in use: ToProcessor, RemoteAddrInNetwork, RemoteAddrNotInNetwork,
RecipientIsLocal, HostIsLocal and two custom Mailets: Log and ChangeRecipientDomain
And one question: why does the value of the From field matter?
Please help!
Thanks
Hes.
