Release 1.1, first posting

Note: Unless otherwise noted in this document or the Getting Started Guide, all known limitations from previous releases and maintenance packs have been resolved in Release 1.1.

2. Introduction

These Late News provide critical information you need to know before and just after installing the Caldera Volution Messaging Server Release 1.1 (hereafter "Messaging Server").

This document assumes you have already read the Messaging Server Cover Letter, which is included with your distribution media. You should also familiarize yourself with these Late News before:

4. Known Limitations and Workarounds

Unless otherwise noted, all known limitations reported in this section will be fixed in a future release.

4.1. Installation

4.1.1. Open UNIX 8 Supplement

The Getting Started Guide erroneously recommends that you install the ou800pk2 (Open UNIX 8 Release 8.0.0 Maintenance Pack 2) supplement and ptf8003 (Connectionless connect fix on Linux AF_UNIX sockets) patch before installing the Messaging Server on your Open UNIX 8 system. They have been superceded by Open UNIX 8 Release 8.0.0 Maintenance Pack 4 (ou800pk), which includes new updates as well as fixes from previous supplements. You must install the Maintenance Pack after installing LKP to ensure that the LKP fixes in the Maintenance Pack are installed. It is not necessary to remove previous supplements before installing Maintenance Pack 4.

It is available from the:

Caldera website 

http://www.sco.com/support/ftplists/ou8list.html

Caldera ftp site 

Enter ftp -p ftp.sco.com and change directories (cd) to pub/openunix8.

Note: You must invoke ftp in passive mode (that is, with the -p option).

Before installation, familarize yourself with the supplement cover letter. If you have already installed the Messaging Server on your Open UNIX 8 system, the supplement and patch can be safely installed after the Messaging Server has been installed and configured.

4.2. Removal

At this time, there are no known removal problems.

4.3. Server Configuration and Administration

4.3.1. Enabling Local System Users to Receive Mail With the Messaging Server

By default, if a user has a Caldera OpenLinux or Open UNIX 8 system account with the User ID as their Messaging Server account, their mail will be delivered to /var/mail/username rather than to a Messaging Server mailbox. However, you can modify your Postfix configuration to enable them to receive mail from the Messaging Server. To do so:

  1. As root, edit the file /etc/postfix/main.cf, making the following changes:

    • Comment out the fallback_transport parameter to read:

          #fallback_transport = cyrus

    • Un-comment the mailbox_transport parameter to read:

          mailbox_transport = cyrus

    • Modify the alias_maps parameter to read:

          alias_maps = ldap:ldapsource, hash:/etc/postfix/aliases

  2. Edit the /etc/postfix/aliases file and add the line:

        root: admin

  3. Initialize the alias database by running the command:

        newaliases

  4. Restart the postfix daemon with the commands:

        postfix stop
        postfix start

When this proceedure is complete, mail will only be delivered to Messaging Server users, not system users. In addition, all administrative system email will go to the Messaging Server admin account.

4.4. Client Configuration and Administration

At this time, there are no known client administration problems.

5. Documentation Notes

5.1. Licensing the Messaging Server

"Licensing" in the Getting Started Guide describes some of mail server configurations available for the Messaging Server, although others might also be available in your area. Contact your Caldera representative to design a mail service solution that fits your needs.

5.2. Viewing Documentation in Server Manager Help Screens

The Server Manager includes Help screens that connect to individual topics in the Administrator's Guide. In addition to describing the Server Manager, the Administrator's Guide also includes detailed information about advanced administrative procedures and Messaging Server components. We recommend using the DocView documentation server for viewing this information; some of the Administrator's Guide hotlinks cannot be displayed in the Server Manager Help screens. For more information about DocView, see "Viewing OpenLinux Documentation" in the Getting Started Guide.

5.3. Creating Messaging Server Accounts on Caldera OpenLinux or Open UNIX 8 Systems

The Getting Started Guide erroneously states that you will receive an error when you try to create a Messaging Server accounts on a Caldera OpenLinux or Open UNIX 8 system that already has a local user account with the same User ID. You can successfully create such an account, but their mail will be delivered to /var/mail/username rather than to a Messaging Server mailbox. To enable delivery to a Messaging Server mailbox, follow the procedure described in "Enabling Local System Users to Receive Mail With the Messaging Server" above.
