 Create the sieve script to redirect spam to junk folder
 **/etc/dovecot/sieve/dovecot.sieve**
-If you have a spam filter such as amavis, it will add the header "X-Spam-Flag = yes", with this little sieve all this mail will go to Junk folder in webmail. Very practical because all the users can check their own spam without the need of the server admin.

 ==== Use domain alias as mail alias too ====
 Making a small change in postfix configuration, we can use the domain alias as a mail ailas.
 Being example2.com an alias of example1.com, whenever I create a mailbox in example1.com the same mailbox in example2.com becomes a redirection.

-=== 1. Create a new table in ispcp called quota_dovecot ===
-This will create also the database to store quota
-  mysql -u root -p mysql
-  mysql> USE ispcp;
-  mysql> CREATE TABLE quota_dovecot (
-    username varchar(100) not null,
-    bytes bigint not null default 0,
-    messages integer not null default 0,
-    primary key (username)
-    );
-=== 2. Granting permissions to the sql user ===
-  mysql> GRANT SELECT,INSERT,UPDATE ON imscp.quota_dovecot to 'ispcp_dovecot'@'localhost'
-  mysql> FLUSH PRIVILEGES;
-  mysql> QUIT;
-=== 4. Configure Dovecot ===
-Replace /etc/dovecot/dovecot.conf with the following one (you should backup the original because there are a lot of comments in it explaining all the configuration parameters).
-  cp /etc/dovecot/dovecot.conf /etc/dovecot/dovecot.conf.org
-Then save this content as your /etc/dovecot/dovecot.conf
