I'll also demonstrate theinstallation and configuration of Courier (Courier-POP3* Courier-IMAP)*so that Courier can authenticate against the same MySQL databasePostfix uses. The resulting Postfix server is capable of bSMTP-AUTH/b and bTLS/b and bquota/b. Passwords are stored in bencrypted/bform in the database. In addition to that* thistutorial covers the installation of bAmavisd/b* bSpamAssassin/b and bClamAV/b so that emails will be scanned for spam and viruses.
