The existing code mixes parsing of email header with regular
expression and actual code. Extract the parsing code into a new
subroutine "parse_header_line()". This improves the code readability
and make parse_header_line reusable in other place.
"parsed_header_line()" and "filter_body()" could be used for refactoring
the part of code which parses the header a last time to prepare the
email and send it.
