James SMTP server while redirecting mail sends it to itself rather than to the
destination
------------------------------------------------------------------------------------------
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.

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.
