Hi,
when I send a mail message with attachments using the camel-mail component,
the mail message is composed as "multipart mail message" and all of my
camel-message headers are appended to the mail and being sent.
But when I poll a mailbox full of those messages there is a gap (asymmetry):
The camel-mail component does not read and reconstruct all custom headers
into my camel message as expected.
I looked at the source code of the mail-component (Camel 2.10.3) and think I
have found an inconsistency in the method
protected Map<String, Object> extractHeadersFromMail(Message mailMessage,
Exchange exchange)
of the MailBinding.java class.
The current version only calls mailMessage.getAllHeaders() and does *not*
consider that this could be a multipart content or a nested message. I think
there's lack of some more iterators over BodyParts "part.getAllHeaders()"
and/or IMAPNestedMessages "nestedMessage.getAllHeaders()" to really retrieve
*all* possible custom headers - and finally be symmetric to the mail
creation logic.
...
Object content = mailMessage.getContent();
if ( content instanceof Multipart )
{
// Iterate over BodyParts and get all headers per part
...
}
else if (content instanceof IMAPNestedMessage)
{
// Recursively walk through IMAPNestedMessage, find Multiparts and iterate
over BodyParts and get all headers per part
...
}
Can somebody verify or confirm that ?
Is it possible to extend that class and override this function of that
component somehow - or do I have to write a custom mail-component ? Maybe
this will be fixed in a future version of camel ? ...
Best regards
