@bbende
Was aware of that possibility. What I couldn't find is a way of easily
doing the same from Expression Language. It would be nice to be able to access
the flowfile lineage from expression language.
Anyhow, initial processor is ready and with test harness. Working on
ExtractEmailAttributes.
@joewitt: ExtractEmailAttributes will have the attributes:
* email.headers.To
* email.headers.From
* email.headers.Message-ID
* email.headers.Date
* email.headers.Subject
* email.attachment_count
Plus the options of:
A. Choosing what attributes get extracted and adding them to
* email.headers.matched_name_here;
B. OR extract all headers under
* email.headers.*
I fear the second option is a terrible security choice (import something
you don't have much control over but I'll leave that to the user to judge)
