John Yin created CAMEL-24848:
--------------------------------
Summary: The useHeaderFrom and other useHeaderXXXXX options
defaulted to false but the document said the default should be true
Key: CAMEL-24848
URL: https://issues.apache.org/jira/browse/CAMEL-24848
Project: Camel
Issue Type: Bug
Components: camel-mail
Affects Versions: 4.22.0
Reporter: John Yin
In 4.22, a number of endpoint options are introduced for the camel mail
component, such as useHeaderFrom, useHeaderRecipients, useHeaderSubject, ...
It is not clear what their default values are - the document is ambiguous. The
document said they are "Default to true" but showed "false" in the default
value column. The actual default value seems to be false. This forces the
application to add a long list of options to the endpoint if the headers are to
be used:
useHeaderFrom=true&useHeaderRecipients=true&useHeaderSubject=true&useHeaderReplyTo=true
Otherwise, the email may be sent to the wrong place or rejected by SMTP server.
The following is copied from smtp.json in camel-mail-4.22.0.jar.
"useHeaderFrom": { "index": 33, "kind": "parameter", "displayName": "Use Header
From", "group": "producer", "label": "producer", "required": false, "type":
"boolean", "javaType": "boolean", "deprecated": false, "autowired": false,
"secret": false, {*}"defaultValue": false{*}, "configurationClass":
"org.apache.camel.component.mail.MailConfiguration", "configurationField":
"configuration", "description": "Whether message headers From and Sender
override the sender pre-configured in the endpoint URI. {*}Defaults to true{*}.
Set to false to always use the endpoint URI sender, ignoring any From or Sender
headers from the message." },
