This documentation is for Dovecot v1.x, see wiki2 for v2.0 documentation.

User extra field

This is mostly useful in case-insensitive username lookups to get the username returned back using the same casing always. Otherwise depending on your configuration it may cause problems, such as /var/mail/user and /var/mail/User mailboxes created for the same user.

An example password_query in dovecot-sql.conf would be: 

# '\' line splitting works only in v1.1+
password_query = \
  SELECT concat(user, '@', domain) AS user, password \
  FROM users \
  WHERE user = '%n' and domain = '%d'

With v1.1+ you can update the user and domain parts separately using "username" and "domain" fields.
