NAMEĭoveadm-sync - Dovecot's two-way mailbox synchronization utilityĭoveadm-backup - Dovecot's one-way mailbox synchronization utility SYNOPSISĭoveadm sync -d| destinationĭoveadm backup -d| destination DESCRIPTIONĭsync is Dovecot's mailbox synchronization utility. This is why the man page for doveadm-sync is being shown below. To read the man page for doveadm-backup in Linux: ~]$ man 1 doveadm-backup NOTE: This is an alias!ĭoveadm-backup is actually an alias of doveadm-sync. So we need to use an SQL query for the userdb again.Linux Home > Manual Sections > 1 > doveadm-backup doveadm-backup(1) - Linux Man Page That conflicts with using the quota plugin though. Previous versions of the ISPmail guide used the static method for userdb. And another for the passdb that gets the hashed password. One for the userdb that gets information like the user ID, group ID, home directory and quota. passdb: which password hash the user hasīy default Dovecot will run two queries at your database.userdb: where to find a user’s mailbox in the file system.Now Dovecot reads the which defines how to find user information in your database. But we want to use the MariaDB database backend so go ahead and change this block to: #!include By default it will use system users (that are listed in /etc/passwd). By default Dovecot sets “disable_plaintext_auth = yes” which ensures that authentication is only accepted over TLS-encrypted connections.Īt the end of this file you will find various authentication backends that Dovecot ships with. These are plaintext (unencrypted) ways to transmit a mail user’s password. However if you have Outl**k users then you need to add the LOGIN mechanism, too.: auth_mechanisms = plain login The most common authentication mechanism is called PLAIN. Those other files in conf.d/ however need a few changes… conf.d/ nf The main /etc/dovecot/nf file does not require any changes. The big advantage is that you can edit or replace parts of the configuration without having to overwrite the entire configuration. So “nf” is loaded first and “nf” is loaded last. It loads all files in /etc/dovecot/conf.d/ that end on “.conf” in alphanumerical order. This is done by this magical line in the nf file: !include conf.d/*.conf The configuration files for Dovecot are found in /etc/dovecot/conf.d/. If the /var/vmail directory was already there because you assigned it a dedicated mount point then you should make sure that the permissions are set correctly: chown -R vmail:vmail /var/vmail Useradd -g vmail -u 5000 vmail -d /var/vmail -m (Make sure that UID and GID are not yet used or choose another – the number can be anything between 100 that is not yet used): groupadd -g 5000 vmail 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. allows the user to fetch emails using POP3 or IMAPīefore we get to the actual configuration for security reasons I recommend that you create a new system user that will own all virtual mailboxes.move emails to different folders based on certain criteria or to send automated vacation responses) executes user-based sieve filter rules (can be used to e.g.gets emails from Postfix and saves them to disk.This chapter of our journey leads us to Dovecot – the software that…
