MailEndpoint requires username/authentication

[Doug Douglass]

Hello All,

I'm using Camel 1.4.0, trying to setup an smtp endpoint to send an email via
Spring xml, note that the smtp server in question does not require any
authentication:

 <camelContext xmlns="http://activemq.apache.org/camel/schema/spring";
trace="true" >
    <route>
      <from uri="seda:eventProcessingErrors" />
      <setHeader headerName="from">
        <el>${"<![CDATA[...]]>"}</el>
      </setHeader>
      <setHeader headerName="subject">
        <el>${"<![CDATA[...]]>"}</el>
      </setHeader>
      <setHeader headerName="to">
        <el>${"<![CDATA[...]>"}</el>
      </setHeader>
      <to uri="smtp://localhost" />
    </route>
  </camelContext>

The smpt component doc[1] implies that user-info/username is not required,
but the plain smtp uri above results in a NPE in
MailConfiguration.createJavaMailProperties() when attempting to put the null
username into the Properties.

Providing a fake user-info (smtp://[EMAIL PROTECTED]) results in, some what
expectedly, authentication exceptions.

So, should MailConfiguration ignore null user-info/username and not try to
put them in the JavaMail Properties?

TIA,
Doug
