For administrators, moving PocoMail installation from one computer to another is as simple as copying the install directory, as PocoMail does not install any DLLs on the user's computer. Mailboxes are kept in the standard mbox format, address books and filters are in the standard CSV format. With PocoScript, you can extend PocoMail's functionality without having to program external DLLs or plug-ins. PocoScript has access to all message parts so you can do advanced processing of incoming mail, like stripping HTML content, or zipping attachments.
