+--   MySQL note ( http://dev.mysql.com/doc/mysql/en/storage-engines.html ):
+--     ENGINE is the preferred term, but cannot be used before MySQL 4.0.18.
+--     TYPE is available beginning with MySQL 3.23.0, the first version of
+--     MySQL for which multiple storage engines were available. If you omit
+--     the ENGINE or TYPE option, the default storage engine is used.
+--     By default this is MyISAM.
+--
+--  Please create additional indexes on keys when needed, or drop suggested
+--  ones as appropriate to optimize queries needed by a management application.
+--  See your database documentation for further optimization hints. With MySQL
+--  see Chapter 15 of the reference manual. For example the chapter 15.17 says:
+--  InnoDB does not keep an internal count of rows in a table. To process a
+--  SELECT COUNT(*) FROM T statement, InnoDB must scan an index of the table,
+--  which takes some time if the index is not entirely in the buffer pool.
+--
+--        Wayne Smith adds: When using MySQL with InnoDB one might want to
+--  increase buffer size for both pool and log, and might also want
+--  to change flush settings for a little better performance. Example:
+--    innodb_buffer_pool_size = 384M
+--    innodb_log_buffer_size = 8M
+--    innodb_flush_log_at_trx_commit = 0
+--  The big performance increase is the first two, the third just helps with
+--  lowering disk activity. Consider also adjusting the key_buffer_size.

+#           will need write access to that directory.
+#  dotlock_try: Same as dotlock, but if it fails because of permissions or
+#               because there isn't enough disk space, just skip it.
+#  fcntl  : Use this if possible. Works with NFS too if lockd is used.
+#  flock  : May not exist in all systems. Doesn't work with NFS.
+#  lockf  : May not exist in all systems. Doesn't work with NFS.
+#
+# You can use multiple locking methods; if you do the order they're declared
+# in is important to avoid deadlocks if other MTAs/MUAs are using multiple
+# locking methods as well. Some operating systems don't allow using some of
+# them simultaneously.

+# new mails. If this setting is enabled, Dovecot does this but still safely

+
+# Quota limits are set using "quota_rule" parameters. To get per-user quota
+# limits, you can set/override them by returning "quota_rule" extra field
+# from userdb. It's also possible to give mailbox-specific limits, for example

+
+# You can execute a given command when user exceeds a specified quota limit.
+# Each quota root has separate limits. Only the command for the first
+# exceeded limit is excecuted, so put the highest limit first.
+# The commands are executed via script service by connecting to the named
+# UNIX socket (quota-warning below).
