LAMP install with Virtual domains and users

[eevans]

I installed LAMP based on this web site, http://www.tecmint.com/setup-postfix-ma … in-centos/, and I can send email anywhere and my server receives email, but the users on the server never get mail delivered. It's stuck in a queue. I am researched this to death and can't find an answer.
At first I got the error "postfix/qmgr[10861]: warning: connect to transport private/dovecot: Connection refused".
Now after much research and config changes and unchanges I get "mail postfix/master[5442]: warning: process /usr/libexec/postfix/pipe pid 5466 exit status 1".
Email is setting on the server and not being delivered to the mailboxes on the server.
Internal delivery is failing, but external delivery is working. I can reply to a message sent to an external email and it comes back to the server and sits there and is never put in the inbox for the user.

I really need to get this resolved and any help would be greatly appreciated.

Without going over what you posted - I can tell you this guide here works and has steps to test it once done - see https://www.linode.com/docs/email/postf ... n-centos-7

You can go over the two and look for what you might have missed or did wrong
