These postings aim to reduce the number of repeated questions as well as allow the community to review and update the answers. The latest version of the complete perlfaq is at http://faq.perl.org . -------------------------------------------------------------------- 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. If you'd like to help maintain the perlfaq, see the details in perlfaq.pod. |
