Installing and setting up Dovecot in RHEL 4 or CentOS 4 is easy. All we have to do is to enable the services we would like to provide and we are good to go.
Install Dovecot
1. If you did not add dovecot during the CentOS installation, you can add it now. Dovecot is located in the package Mail Server. Learn how to add or remove applications here.Configure Dovecot
1. Click Applications then click File Browser. This will launch the File Browser window.
2. In the Location field, type in /etc and press Enter.
3. Double click on the file dovecot.conf to open it for editing. We need to change a few key items.Find the following keys and change its values as follows
protocols = pop3 pop3s imap imaps default_mail_env = maildir:~/Maildir/ client_workarounds = oe6-fetch-no-newmail outlook-idle outlook-pop3-no-nuls
Lines starting with # are comments. The last line enables workarounds for various Microsoft Outlook/Outlook Express bugs. Save the file after completing your changes.
4. Start the dovecot service. Learn how to start and stop services here.Test Dovecot
1. Click Applications, select System Tools, and click Terminal. This will launch the Terminal window.
2. In the Terminal window, type in the highlighted commands below.Sample dovecot session. Replace johndoe and password with any valid user name and password.
[root@mail ~]# telnet localhost pop3 +OK dovecot ready. user johndoe +OK pass password +OK Logged in. list +OK 1 messages: 1 622 . retr 1 +OK 622 octets Return-Path: <johndoe@mail.acme.local> X-Original-To: johndoe Delivered-To: johndoe@mail.acme.local Received: from localhost.localdomain (localhost.localdomain [127.0.0.1]) by mail.acme.local (Postfix) with SMTP id 9729067C17 for <johndoe>; Thu, 22 Feb 2007 09:06:37 -0500 (EST) Message-Id: <20070222140640.9729067C17@mail.acme.local> Date: Thu, 22 Feb 2007 09:06:37 -0500 (EST) From: johndoe@mail.acme.local To: undisclosed-recipients:; X-IMAPbase: 1172153557 1 Status: O X-UID: 1 Content-Length: 5 X-Keywords: test . quit +OK Logging out.

I’ve got the same problem, and I opened the error log, it shows:
Jul 15 21:30:46 regulus dovecot: imap-login: Login: user=, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured
Jul 15 21:30:46 regulus dovecot: IMAP(jandura): Disconnected: Logged out
I can send email to any email, but I couldn’t receive email from any mails except my own machine!

Check your postfix settings. Mydestination should be something like the one below.
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
