Upgrading Dovecot v1.1 to v1.2

  • Relative home directory paths are giving errors now. They were never supported, but earlier they just didn’t usually cause problems.

    • If you were using e.g. mail_location = maildir:/var/mail/%h, just change it to mail_location = maildir:%h and add /var/mail/ prefix to home dirs.

    • To get absolute home dir from relative path in LDAP, use something like: user_attrs = .., homeDirectory=home=/var/mail/%$

  • SQL dictionary (quota, expire plugin) configuration file is different than in v1.1. See doc/dovecot-dict-sql-example.conf or for the new format.

  • When creating files or directories to mailboxes, Dovecot now uses the mailbox directory’s permissions and GID for them. Previous versions simply used 0600 mode always, so you should check the directories’ permissions to make sure they’re strict enough. For backwards compatibility dovecot-shared file’s permissions still override these with Maildir.

Authentication:

Settings:

  • Renamed ssl_disable=yes to ssl=no.

  • Renamed auth_ntlm_use_winbind to auth_use_winbind, which also determines if GSS-SPNEGO is handled by GSSAPI or winbind.

  • Removed login_greeting_capability. The capabilities are now always sent <LEMONADE requires this and it’s not that much extra traffic).

  • Removed auth_worker_max_request_count. It was useful only with PAM, so it can now be specified in passdb pam { args = max_requests=n }. The default is 100.

  • Removed umask. It wasn’t really used anywhere anymore.

ACL:

  • The global ACL file overrides per-mailbox ACL file.

Sieve:

ManageSieve:

  • The sieve and sieve_storage settings need to be placed in the plugin {} section now and sieve_storage needs to be renamed to sieve_dir. This removes the duplication of these values with respect to the Sieve Plugin for Deliver. So, since you are using the Sieve plugin, these settings should already be there and all that needs to be done is remove the sieve= and sieve_storage= settings from the protocol managesieve {} section.
