9.15: How do I parse a mail header?

    For a quick-and-dirty solution, try this solution derived from "split"
    in perlfunc:

            $/ = '';
            $header = <MSG>;
            $header =~ s/\n\s+/ /g;  # merge continuation lines
            %head = ( UNIX_FROM_LINE, split /^([-\w]+):\s*/m, $header );

    That solution doesn't do well if, for example, you're trying to maintain
    all the Received lines. A more complete approach is to use the
    "Mail::Header" module from CPAN (part of the "MailTools" package).


The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
