> Email processors with Exchange don't output to RFC2822 format

> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.0.0

> Reporter: Emil Frank

> When using the new ConsumeIMAP and ConsumePOP3 processors with a Microsoft
> Exchange 2013 IMAP server the flowfiles which are produced are simple HTML
> messages with no RFC2822 headers. I have also tried setting Exchange to force
> emails to be text only, sadly only the body with some Content-Type: fields
> are outputed.
> This mean that ExtractEmailHeaders and ExtractEmailAttachments cannot be used
> directly with these processors.
> In Python, I can force Exchange to output the headers by specify RFC822 in
> the connection settings:
> - https://docs.python.org/3/library/imaplib.html#imap4-example
> Is a similar option available for the spring mail framework?
