Most tutorials on UNIX mail services skip section related to mail directories. However joe’s (you can get his book Unix for the Beginning Mage here) tutorial starts with /var/spool/mail directory and it further explains the difference between mbox (an electronic mail file format) and maildir format. It explains fundamentals in joe’s own classic style 🙂

“maildir?”
