+--
+-- * if you're running RHEL/CentOS 6 or 7, don't forget to uncomment lines
+--   under `Required by RHEL/CentOS X` to create dblink function.
+--
+-- * of course you should replace `xxx` in below sample SQL command by the
+--   real SQL username/password/database name.
+--
+-- * it's better to use SQL user `vmail` which has read-only permission to
+--   `vmail` database. Don't use `vmailadmin` or `postgres` user.

+-- Known issue on iRedMail server:
+--
+-- * Column `mailbox.created` stores timestamp when this account was created,
+--   if the timestamp contains timezone info (e.g. 2015-02-28 22:31:16.562376),
+--   this plugin cannot display any contact (causes SQL syntax error).
+--   Changing the timestamp to 2015-02-28 22:31:16 (without time zone info)
+--   fixes this issue.
