Internet Express for Tru64 UNIX Version 6.8 Installation Guide (14234)

Mail folder names are constructed using the slash (/) as a separator, usually as children of the
top-level mail directory (for example, mail/save/stuff). The UW-IMAP server uses the special
name INBOX for the user's mail spool file, which is the name expected by all mail clients.
The Cyrus server does not require a top-level mail directory. Folder names are constructed using
the period (.) as a separator and are generally children of the INBOX folder (for example,
INBOX.save.stuff).
2.19.3 Administrative Overhead
The UW-IMAP server requires no administrative overhead. Any user who can be authenticated
has access to mail folders under his or her home directory.
Before a user can use the Cyrus IMAP server, the user's existing mail folders must be converted
to the Cyrus format. The Internet Express kit includes a modified version of the Tru64 UNIX
mail conversion utility, /usr/internet/mail/bin/mailcv, which can convert UNIX (“From”
style) folders to the Cyrus format and vice versa. See the Administration Guide for information
on how to use the modified version of the mailcv utility. You can read the reference page for
the modified version of the mailcv utility by entering the following command:
% man n mailcv
2.19.4 Mail Folder Sharing
Cyrus supports the use of access control lists (ACLs) to allow customized access to mail folders.
The ACLs provide a means of allowing users to share mail folders with a user-specific level of
privileges.
Cyrus also supports the creation of common folders (that is, folders that are not specific to a
given user). Visibility and access to common folders are controlled through ACLs.
With Cyrus, folders can be accessed concurrently by more than one mail client (even by different
users).
The UW-IMAP server does not support ACLs or shared write access to folders. If a second client
opens a mail folder that another client has open, the first client's connection is closed.
2.19.5 Disk Quota Management
Cyrus supports disk quota management, allowing for automated management of the disk space
allocated to users' mail. When the disk quota for a user's mail would be exceeded by the receipt
of a mail message, the message is automatically rejected.
UW-IMAP does not provide automated disk quota management.
2.20 Configuring the OpenLDAP Server
The installation procedure prompts for the following information required to set up the
OpenLDAP Directory Server:
• Searchbase (otherwise known as organization name)
• Root Distinguished Name (rootdn)
• Root password (rootpw)
Defaults for all of the above are provided as follows:
1. If an existing OpenLDAP installation is detected, the existing configuration information is
used.
2. If no prior installation exists, but the LDAP Module for System Authentication has been
installed and configured on this system, default values are taken from /etc/ldapcd.conf.
3. If neither of the above are true, then the default searchbase is set to o=<hostname>, where
hostname is the name of the local system. The root dn is set to root. The rootpw is set to
the password specified at the beginning of the installation (if it is 8 characters long), otherwise,
