Move header filtering from MimeMessageParser to EmailConverter, thereby enabling access to all parsed headers when using MimeMessageParser directly #487
Description
Hi, first of all, thank you for this great library.
I'm opening this issue to ask if there are any possibility to tweak the ignored headers list used by the MimeMessageParser.
I'm asking this because I'm in a situation where I need to parse an .eml file and retrieve all the "Received" headers.
After a bit of debugging I found the HEADERS_TO_IGNORE list in MimeMessageParser.java which contains all the ignored headers.
Is there any possibility to customize this behaviour?
Thanks in advance!
