Dovecot Debian package ====================== Please refer to http://wiki2.dovecot.org for the full documentation of this package and its configuration. Note that the default value for mbox_write_locks differs between Debian and upstream Dovecot: Debian: mbox_write_locks = "fnctl dotlock" Dovecot: mbox_write_locks = "dotlock fnctl" TLS setup --------- TLS is enabled by default on new installations. Dovecot will use the self-signed certificate provided by ssl-cert-snakeoil by default. The certificate and key are accessed via symbolic links in /etc/dovecot/private. If you wish to use your own certificates, feel free to replace the symbolic links in /etc/dovecot/private with the actual certificate/key of your preference, or place the certificate and key at the location of your preference and update /etc/dovecot/conf.d/10-ssl.conf accordingly. dovenull group -------------- Upstream recommends that for security's sake, the dovenull user should belong to its own private group to which no one else belongs. Prior to 2.2.9-1, the dovenull user was in the nogroup group which contains other users. This has been rectified for new installs but upgraders should make the change themselves like this: # addgroup --system --group dovenull # usermod -g dovenull dovenull
