Description

I get the following exception in RemoteDelivery.getGatewaySMTPHostAddresses():

java.lang.NullPointerException
at org.apache.james.transport.mailets.RemoteDelivery$1.hasNext(RemoteDelivery.java:1331)
at org.apache.james.transport.mailets.RemoteDelivery.deliver(RemoteDelivery.java:453)
at org.apache.james.transport.mailets.RemoteDelivery.run(RemoteDelivery.java:1098)
at java.lang.Thread.run(Thread.java:595)

in hasNext(), the break condition is not complete (missing addresses == null check)

I'm working on a patch.

RemoteDelivery config in question:
