How do I restart dovecot IMAP4 / IMAP (Internet Message Access Protocol) under RHEL / CentOS / Fedora / Debian / Ubutnu Linux?

The Internet Message Access Protocol is a standard client / server protocol for accessing e-mail from your local server. It will not just retrieve email but view it and manipulate it on the server itself. IMAP4 clients can create, rename, and/or delete mailboxes (usually presented to the user as folders) on the server, and move messages between mailboxes. Multiple mailbox support also allows servers to provide access to shared and public folders.

=> The default IMAP server port number: 143
=> Under Linux you can install different IMAP servers.
