Mail sending through gmail in Mule Flow - smtp

Question

I am struggling with mail sending flow in mule, Getting below error:
Failed to route event via endpoint: DefaultOutboundEndpoint{endpointUri=smtps://dummy.DevGroup:<password>#smtp.gmail.com, connector=SmtpsConnector
I have below configuration in my xml file (Updated with namespace declarations in the Mule XML):

I updated the xml file as below content, to use smtp-gmail-connector given here

<outbound>

replyToAddresses="iip.claims.test#gmail.com" >
<smtp:header key="foo" value="bar" />
<smtp:header key="baz" value="boz" />
</smtp:gmail-connector>
But after this I am getting below error:

Any help will be appreciated.

Answer 1

There are many details missing however on rereading the issue I suspect you are not following the deprecated syntax <service> correctly by trying to use a current example. Since that syntax has been deprecated for 6+ years, I would advice to move to the more current <flow> definitions.
In case you are unable or unwilling to migrate, you need to define an endpoint outside the service and reference it you could try the following steps:
Ensure that the namespaces at the beginning of the file are correct. The error mentions that doc: is not recognized. Maybe the namespaces are outdated.
Ensure that the dependencies in the pom reference your Mule 3.9.x release and not an older version that may not define doc.
Try moving <smtp:outbound-endpoint> to a separate endpoint definition and reference it from the <pass-through-router> as in your original implementation.
Example:
<service name="tool.muleservice.emailServiceintegration">
<inbound>
<inbound-endpoint ref="tool.endpoint.emailNotification"/>
</inbound>
<outbound>
<pass-through-router>
<outbound-endpoint ref="tool.smtp.endpoint.gmailNotification"/>
</pass-through-router>
</outbound>
</service>
<smtps:endpoint name="tool.smtp.endpoint.gmailNotification"
connector-ref="smtpGmailConnector"
subject="test msg"
address="smtps://#[message.inboundProperties['userName']]:#[message.inboundProperties['password']]#smtp.gmail.com"
responseTimeout="10000" doc:name="Send notification email" >
</smtps:endpoint>
<smtp:gmail-connector name="smtpGmailConnector"
contentType="text/html" fromAddress="iip.claims.test#gmail.com"
replyToAddresses="iip.claims.test#gmail.com" >
<smtp:header key="foo" value="bar" />
<smtp:header key="baz" value="boz" />
</smtp:gmail-connector>
Finally if everything else fails you could try removing the doc:name attribute and see what happens.
