Where to find accurate, clear tutorial on installing and setting up Dovecot+Postfix+SquirrelMail where can I find it?

Guys, two days into reading all sorts of guides on this ligament and can't find the manual, after which the server starts mail =(

Need a bunch of Dovecot+Postfix+SquirrelMail on Ubuntu 14.04 desktop x64, the server is in local network, with Internet access (limited channel). Need to make mail server IMAP/POP3 for resources in local area network (messaging + on many sites through my server password recovery). We can confine ourselves to the local network, ie no access to the Internet.

On the server which is a mail server already installed: 2.3 Apache, MySQL, PHP with configured sites (virtual hosts and forums). Was already one of the stones on which I stumbled while installing iRedMail - flew the whole Apache server =(

Thanks in advance.
