Anastasia Tugaenko commented on JAMES-1018:
-------------------------------------------
The problem is that James server doesn't recognize that next translation will
be to itself. So it sends mail to itself all allowed number of times. And also
it doesn't send the notification about undeliverable of message to the
originator.

> Key: JAMES-1018
> URL: https://issues.apache.org/jira/browse/JAMES-1018
> Project: JAMES Server
> Issue Type: Bug
> Components: SMTPServer
> Affects Versions: 2.3.1
> Environment: Windows XP
> Reporter: Anastasia Tugaenko
> Priority: Minor
>
> Under certain network and DNS configuration James SMTP server version 2.3.1
> sends mail to itself rather than to the next hop. As a result, the mail loops
> until resending limit is exceeded. It never gets to the destination.
>
> Configuration
> The configuration file - http://www.ispras.ru/ru/james/config.xml.
> The issue was reproduced in a virtual network with three nodes and two
> domains (see http://www.ispras.ru/ru/james/virtualNet.png):
> 1. network vbox1.test with nodes XP11 and XP12,
> 2. network vbox2.test with nodes XP21 and XP22;
> 3. nodes XP11 and XP21 are physically on the same virtual machine where
> James SMTP server runs. DNS runs on the same server.
> DNS configuration used to reproduces the issue is available here -
> http://www.ispras.ru/ru/james/etc.zip.
> The issue occurs when MX record for XP21 has higher priority than that of
> XP22.
> XP22 IN MX 15 XP21
> XP22 IN MX 25 XP22
> Steps to reproduce the issue:
> 1. Turn on the virtual machines for nodes XP11/XP21, XP12, XP22. Launch DNS
> and James SMTP on the XP11/XP21 virtual machine. Launch mail agents on XP12
> and XP22.
> 2. Send a mail from XP12 to XP22 (e.g. to [email protected]).
>
> Issue:
> Mail agent on XP12 sends the mail to the James SMTP server on XP11. The James
> SMTP server re-sends the mail to itself (the MX record priority is higher
> than that of XP22). As a result the mail never arrives to XP22.
> James SMTP log is available here -
> http://www.ispras.ru/ru/james/smtpserver.log.

> Mail1276088212910-3 from [email protected] on 192.168.209.21 for
> [[email protected]]
> The log shows that the mail gets constantly re-sent from XP11 to XP12 (the
> same physical machine) and never arrives to the destination. We tried other
> open-source SMTP servers in the same configuration - they do not loop and
> deliver the mail to the next hop.
