For cPanel & WHM 11.46

(Home >> Service Configuration >> Mailserver Selection)


This interface allows you to select either Courier or Dovecot as your mail server. You may also choose to disable IMAP and POP3 services entirely.

Courier is the traditional IMAP server that cPanel installs, and it is extremely reliable. However, Dovecot uses less memory, provides better performance, and has more configuration options.

Select or disable a mail server

To select or disable a mail server, perform the following steps:

  1. Select CourierDovecot, or Disabled.
  2. If you wish to preserve users’ mailbox settings, such as subscriptions to mailing lists and message read flags, select the Convert mailbox settings… checkbox.


    If you choose not to preserve the users' mailbox settings, it may result in faster migration between mail servers.

  3. Click Save.
