+
−      (ex. psql mailsys mailsys vmm -W -h localhost)
+
−    * update the database: \i update_tables_0.4.x-0.5.pgsql
+
−    * GRANT SELECT ON postfix_alias TO postfix;
+
−                                       ^^^^^^^^ <- your Postfix db user
+
−

−
+
−  Dovecot v1.2.x
+
−    -> Are you already using Dovecot v1.2.x?
+
−       * update the database for Dovecot v1.2.x:
+
−         \i update_tables_0.5.x_for_dovecot-1.2.x.pgsql
+
−       * GRANT SELECT ON dovecot_password TO dovecot;

+
−         \i update_types_and_functions_0.5.x_for_dovecot-1.2.x.pgsql
+
−
+
−       * You have also to adjust the permissions of the set-uid deliver copy:
+
−         on BSD:
+
−           chgrp nobody /usr/local/lib/dovecot/deliver
+
−         on Linux:
+
−           chgrp nogroup /usr/local/lib/dovecot/deliver
+
−         chmod u+s,o-rwx /usr/local/lib/dovecot/deliver
+
−
+
−       * Check the master.cf from Postfix.
+
−         In prior setups the service dovecot was configured slightly different.
+
−         If you have set the command attribute 'user' to 'nobody:mail', so
+
−         either remove the group mail or replace it with the group nobody
+
−         or nogroup.
+
−
+
−         e.g.: flags=DRhu user=nobody argv=/usr/local/lib/dovecot/deliver …
