Shell Scripting for Dovecot configuring in Linux

Dovecot is an open-source IMAP and POP3 server for Linux/UNIX-like frameworks, composed essentially with security in mind. Timo Sirainen began Dovecot and first discharged it in July 2002. Dovecot engineers basically mean to deliver a lightweight, quick and simple to-set-up open-source mailserver.
