Integrating IMAP, LDAP, and Postfix on Debian

Buffy is the codename for this detailed and complete recipe on creating an advanced mail system using debian, ldap, courier and postfix.

• Database Storage: ldap for storing users, mysql for storing user preferences.
• Mail Transport Agent: postfix.
  
• Mail Delivery Agent: maildrop.
  
• Mail User Agent: courier-imap.
  
• Mail Clients: pine, mutt, squirrelmail, imp.
  

• web based admin: administrators can perform almost all account management functions from an easy web interface.
• web based user settings: end users have a easy to use control panel to manage their account settings.
• protocals: imap, imaps, pop, pops, smtp, smtps, http, https.
• quota support: each user has a quota, stored in a database, which is enforced.
  
• mail filtering: all incoming mail can be filtered for spam or viruses. users can write their own global filters.
  
• high performance: each software package used is either the fastest free software package available or close to it.
• multiple servers: multiple machines can divide up the mail load, each responsible for a different subset of users.
  
• virtual users: mail accounts are only mail accounts and not login accounts stored entirely in ldap.
