I personally believe that once again I have a problem for which (more than) a very simple module (in terms of UI) must be provided, except that I can't find a suitable one, most probably due to a misunderstanding on my part.
Indeed a Mailbox search gives me quite a lot of hits, but to help you to help me I must be more precise about what I want to do. Specifically, I have a series of archived (well, "compressed," more technically) standard *NIX mailboxes and I would like to write a filter that would behave fundamentamentally like this:
bzip2 -qcd saved-messages*.bz2 | ./filter.pl > goodones
Where goodones would still be a *NIX standard mailbox, and filter.pl would select on some headers and the actual message body. I only need a direction on the module to use for this. Any Idea? The modules I found with the previous CPAN search give me the impression of doing "kinda too much" and I'm slightly loss.
