These slides are part of a three hour tutotial, as presented at the YAPC::Europe 2002 conference in München Germany, 18 september 2002.
In the last few years, e-mail developed from an application used by a relatively small scientific community into a basic means of communication for everyone. Companies have added e-mail as a new way to keep in touch with costumers, next to the traditional postal and telephone services. Friends post birthday invitations by e-mail, and the pictures of the last family meeting are broadcasted to everyone on them.
Creative new practices for e-mail include spam and spreading viruses. Jokes are not posted in plain text anymore, but preferably as PowerPoint presentations. Plain text is not nice at all: let's send HTML or -even better- full Word and PDF documents to everyone we know!
The concept of e-mail has changed, and with it the need to control that flow has increased. Filters which automatically remove received spam, virus checkers, and message content converters are more and more implemented. At the same time, mail folders grow rapidly in size. The number of messages to read daily explodes. How to cope with that?
The recently developed Mail::Box module is capable of handling various kinds of mail folders and replaces many older Perl modules (like MailTools) with components which are better suited for the current generation of messages. The module supports many advanced features which can help implementing the filters you need.
Many featurs of Mail::Box, Mail::Address, and MIME::Types are discussed during this presentation. A few small programs are explained.
