Error In Configuration File /etc/dovecot.conf
you are using Debian Jessie! Let us now configure Dovecot which will do several things for us: get emails from Postfix and save them to disk execute user-based "sieve" filter rules (can be used to put away emails to different folders) allow the user to fetch emails using POP3 or IMAP Before we get to the actual configuration for security reasons I recommend that you create a new system user that will own all virtual mailboxes. The following shell commands will create a system group "vmail" with GID (group ID) 5000 and a system user "vmail" with UID (user ID) 5000. (Make sure that UID and GID are not yet used or choose another - the number can be anything between 1000 and 65000 that is not yet used): groupadd -g 5000 vmail useradd -g vmail -u 5000 vmail -d /var/vmail -m Also make sure that this directory has the proper permissions: chown -R vmail:vmail /var/vmail chmod u+w /var/vmail The configuration files for Dovecot are found under /etc/dovecot. In previous guides there were only two configuration files. But in Debian Wheezy's Dovecot version you will find a new directory "conf.d" that contains about 30 configuration files. All these files are joined together to form the complete Dovecot configuration. This is done by this magical line in the dovecot.conf file: !include conf.d/*.conf It loads all files in /etc/dovecot/conf.d/ that end on ".conf" in sorted order. So "10-auth.conf" is loaded first and "90-quota.conf" is loaded last. The big advantage is that you can edit or replace parts of the configuration without having to overwrite the entire configuration. The disadvantage is that if you are upgrading your mail server from a previous Debian version that you need to re-configure everything in Dovecot. The main /etc/dovecot/dovecot.conf file does not require any changes. These other files in conf.d/ however need to be edited… conf.d/ 10-auth.conf If you expect your users to use Micro$oft Outlook as an email application you should enable the "LOGIN" authentication mechanism in addition to the standard "PLAIN" mechanism: auth_mechanisms = plain login These are plaintext (unencrypted) ways to transmit a mail user's password. But don't worry. By default Dovecot sets "disable_plaintext_auth = yes" which ensures that every connection is encrypted using TLS. At the end of this file you will find various authentication backends that Dovecot uses. By default it will use system users (that are listed in /etc/passwd). But we want to use the

But don't worry. By default Dovecot sets "disable_plaintext_auth = yes" which ensures that authentication is only accepted over TLS-encrypted connections.

Because setting up a mail server is tricky, we’ve created this companion troubleshooting guide error in to help you work through and resolve any problems you might be experiencing. By the time you reach the end of this guide, you’ll know how to debug problems with your Postfix, Dovecot, and MySQL mail server. The first section, Troubleshooting Checklist_, has a top-down approach to troubleshooting that will help you find specific errors for your mail server. The second error in configuration section, Step-by-Step Configuration_, uses a bottom-up approach that shows you how to get a basic mail server functioning and then gradually add more features. Troubleshooting Checklist Correctly diagnosing a problem is the first step in solving it. At first glance, many mail server errors can seem quite general. Usually the first sign of a problem is that you try to create a test mail account and can’t connect. This section is a crash course in finding mail server errors. We recommend reading through the following sections in order, because they progress from general to more specific troubleshooting techniques. Are Postfix and Dovecot Running? Sometimes your mail server is not functioning correctly because the needed services are not running. For a mail server that has been running for a long time, resource overuse is the most likely cause of stopped services. It doesn’t hurt to check your resource use to rule out that problem. However, when you’re just setting up a new mail server, it’s more likely that your service startup problems are being caused by configuration errors. Some co

Following this tutorial you'll be able to add virtual domains, users, and aliases. Moreover, your virtual server will be secure from spam hub. Prerequisites Before setting up your mail server, it's necessary your VPS has the following: * Domain is forwarding to your server (setup domain) * MySQL installed and configured (setup mysql) * User with root privileges (setup new users- omit step 5) *Configure and identify your FQDN (setup FQDN) Optional: SSL certificate (setup free signed ssl certificate) Optional ( Log in as root user ) Installing packages as the root user is useful because you have all privileges. sudo -i Introduce your user's password. Once it's successful, you will see that $ symbol changes to #. Step 1: Install Packages apt-get install postfix postfix-mysql dovecot-core dovecot-imapd dovecot-lmtpd dovecot-mysql When Postfix configuration is prompted choose Internet Site: Postfix configuration will ask about System mail name – you could use your FDQN or main domain.
