Maildir

Maildir is a method of storing email messages on a computer. Instead of packing all messages into one big file, it saves each email as a separate individual file within a structured directory system. This organization makes it easier to access, update, or delete individual emails quickly without affecting others. Maildir's design improves performance and reduces corruption risks, especially when multiple programs access the mail storage simultaneously. Overall, it provides a reliable and efficient way to manage email messages digitally.
