Hi,

I am doing a straightforward call to the Camel mail component:

                        Exchange exc = endpoint.createExchange();
                        Message in = exc.getIn();
                        in.setBody(failureEmailBody);
                        Map headers = in.getHeaders();
                        if (headers == null)
                        {
                                headers = new HashMap();
                        }
                        headers.put("From", this.fromEmailAddress);
                        headers.put("To", this.emailAddresses);
                        headers.put("Subject", "TECH PACK EXPORT SYSTEM ERROR");
                        headers.put("contentType", "text/html");
                        in.setHeaders(headers);
                        if (log.isDebugEnabled())
                        {
                                for (Iterator it = headers.keySet().iterator(); 
it.hasNext();) 
                                {
                           String key = (String) it.next();
                           log.debug("Key:" + key + ", Value:" + 
headers.get(key));
                        }
                        }
                        // create a producer that can produce the exchange (= 
send the mail)
                        Producer producer = endpoint.createProducer();
                        // start the producer
                        producer.start();
                        // and let it go (processes the exchange by sending the 
email)
                        producer.process(exc);

In my logging, I see the to and from addresses being set, but I get this in
the logs:

Where is the header or the "to value" getting lost?  This works fine in my
own environment, but on a customer dev env they get this issue.  This is
running as a war under tomcat

Thanks,

Carl
