Body:
This bug was identical to JAMES-236, except for being in the gateway server iterator
instead of the MX hosts iterator in the DNSServer code.

Here is an overview of the issue:
---------------------------------------------------------------------
Key: JAMES-318
Summary: java.lang.NullPointerException when host is unknown
Type: Bug
Status: Unassigned
Priority: Major
Project: James
Components:
Remote Delivery
Versions:

Description:
I encountered the following NullPointerException:
18/08/04 14:29:59 INFO James.Mailet : RemoteDelivery: Unknown gateway
host: unknown host
18/08/04 14:29:59 INFO James.Mailet : RemoteDelivery: This could be a DNS
server error or configuration error.
18/08/04 14:29:59 INFO James.Mailet : RemoteDelivery: Exception caught in
RemoteDelivery.run()
java.lang.NullPointerException
at
org.apache.james.transport.mailets.RemoteDelivery.deliver(RemoteDelivery.java:409)
at
org.apache.james.transport.mailets.RemoteDelivery.run(RemoteDelivery.java:912)
at java.lang.Thread.run(Thread.java:534)
This is caused by logging information about a HostAddress that happens to be null.
The HostAddress is null because I had a misconfiguration in my config.xml: a gateway
server that could not be found.
I fixed the issue for myself by entering the correct host name.
Still, NullPointerExceptions are a bad sign.
Also, the message seems to disappear from the queue. I can't find it in the spool
directory and there is no attempt of delivery after a restart.
In other words, I seem to observe that a message gets lost when this occurs.
