 +====== Mailserver Selection ======
  
 +cPanel offers you a couple options of mailservers to choose from.  You can either log into the WHM and pick and choose or do it from the CLI.  Both ways are methods are explained below.
 +
 +===== Selecting a mailserver through the WHM =====
 +
 +First you need to log into the WHM as the user root.  Once logged in scroll down the left side navigation until you see the 'Service Configuration' category.  From there click on the 'Mailserver Selection' link.  You will now be presented with your mail server options.  We recommend you choose the default mail server, as of writing this article the default server is dovecot.  Select the mail server of choice, scroll down and make sure the convert mailbox format is checked.  Click save and the WHM will now install the new server as well as convert your existing mailboxes to the required format!
 +
 +===== Selecting a mailserver through the CLI =====
 +
 +Log into your servers console as the user root.  Once logged in you can run the command '/usr/local/cpanel/scripts/setupmailserver' to see the available options and mailservers you can choose. We recommend you choose the default mail server which at the time of this article is Dovecot.  Once you have made your decision run '/usr/local/cpanel/scripts/setupmailserver Dovecot' this will go through and install the mailserver as well as convert any existing mailboxes to the new format.
