How to avoid sending message headers with mail component ?
Hi,
I'm querying a database with the iBatis component, then splitting the
resultlist into single messages.
These are sent each to email addresses from the result set - which works
fine and wonderfully easy with the camel mail component.
But when the receiver of that mail will inspect the details or properties of
the received mail, he'll see a lot of headers in the mail (e.g. my
resultlist or BCC header) that I don't want to be neither public nor sent.
Is it possible e.g. by certain parameters to send *nothing but the body* of
the camel message as plain text mail message ?
(I could remove some of my own headers before sending - but what about BCC ?
I'd like to filter out all unwanted headers by configuration to avoid
private data going public incidentially).
Thanks for any help....

Richard that was a good answer.
I added this as a FAQ as its a general question how to remove some/all headers

This is a gotcha more people encounter. However it's very easy to solve. To
remove all headers use a wildcard expression:
from(...).removeHeaders("*").to("smtp://....")
Similarly to remove all headers except some of your own (myheader1 and
myheader2) use a wildcard with a vararg:
from(...).removeHeaders("*", "myheader1", "myheader).to("smtp://....")
Again to remove only Camel headers but no other transport headers:
from(...).removeHeaders("Camel*").to("smtp://....")
I think in your case removeHeaders("*") will suffice.
Good luck!
Regards,
Richard

Hi
Just implement a custom strategy and then register that in the
registry, eg if spring then
<bean id="myCustomFilter" class=...">
And then configure the endpoint or component to use your filter.
?headerFilterStrategy=#myCustomFilter

Hi,
Are there any examples of using a header filter strategy with the camel mail
component?
I can not see this option within the camel-mail page, not in the camel-mail
MailConfiguration.java
I assumed camel might be handle this filtering itself, but this I'm not sure
this is true as the documentation suggests it is on a per-component basis
- "An alternative is that [b]some[/b] of the Camel Components supports
configuring a custom header filter strategy."
http://camel.apache.org/how-to-avoid-sending-some-or-all-message-headers.html
Would appreciate any guidance with this :)
Cheers

Hi
Oh another approach could be to use a custom header filter strategy on
the mail component / endpoint.
That will filter out all the headers, then only the body is being sent.

You can use the wire tap to spawn off a new message (sending a new exchange)
where you only copy the body.
See details at:
http://camel.apache.org/wire-tap.html
Something like
.wireTap("smtp:...", false, simple("${body}"))

Happy new year and thanks for the quick reply !
But what happens in a (simplified) case like this:
from("ibatis:selectUnprocessedAccounts?consumer.onConsume=consumeAccount")
// returns a list of beans with partly private information
.split( ... )
.removeHeaders("*")
// set the message body from bean.text
...
// set the headers to, cc, bcc from bean.email, bean.cc, etc...
...
.to("smtp://...)
// bcc header is also sent in the mail (?)
// message/bean is now consumed, but any reference to the sql
consumeAccount statement (e.g. #id#)
// has gone
.to("mock:results");
As far as I understand, I have to filter out all but the further needed
headers (as "id").
Might there be a way to keep all camel message headers but configure that
*only the body* is mailed ?
(I'm aware that I could always write my own processor)
