Requirements
This topic describes the server requirements for installing the IBM® mail server add-on (IMSA).
System requirements
- 64-bit IBM
Domino® 9.0.1 on Windows with Fix Pack 6 or later.
- See complete requirements at: IBM Domino 9.0.1 Social Edition for Windows
- Review the topic Installing Domino on Windows
OR
- 64-bit IBM
Domino 9.0.1 on AIX with Fix Pack 6 or later.
- See complete requirements at: IBM Domino 9.0.1 Social Edition for AIX®
- Review the topic Installing Domino on UNIX
OR
- 64-bit IBM
Domino 9.0.1 on Red Hat Enterprise Linux (RHEL) with Fix
Pack 6 or later.Note: SUSE Linux Enterprise Server (SLES) is not supported.
- See complete requirements at: IBM Domino 9.0.1 Social Edition for Linux
- Review the topic Installing Domino on UNIX
- IMSA server
Note: The IMSA server should follow the Domino best practice
of upgrading to the latest on-disk structure (ODS); as of Domino 9.0.1
(and subsequent fixpacks), the latest version is ODS52. Additional
information can be found in this technote: Update to "Domino On-Disk Structure" for Domino 9.0.1:
ODS52
Note: In addition to the IMSA server being Domino 9.0.1, the same must be
true for the administration server of the domain. This is because
the Traveler task creates an adminp request that
updates the server document to indicate that the server is now supporting
IMSA. If the administration server is not at Domino 9.0.1 (or greater), then the adminp request
will not get processed, and the server configuration will be incorrect.
Server configuration settings
- $CSUID2APPTUNIDCONTROL=4 - This INI setting impacts
the home mail server, i.e., the server where mail gets delivered,
even if that is not the IBM Mail
support for Microsoft Outlook
server.
- Recommended - The setting is recommended if all servers in the same cluster of the home server are running Domino release 9.0.1 or higher. If all servers are not running Domino release 9.0.1 or higher, there is a remote potential to have rescheduled calendar entries from external, non-Notes meeting organizers appear as invitations. This happens if the original invitation arrives on a 9.0.1 server, and the reschedule notice is delivered to a server earlier than Domino 9.0.1, for example due to failover.
- Required - This INI setting is required on your home server, to ensure successful interoperability with external organizers, especially in cases where there are both AIX and non-AIX servers involved - for example, when an AIX server is the home server, and there is a Windows server that services IBM Mail support for Microsoft Outlook. In such a scenario, counter proposals to external organizers will not work from Outlook.
- HTTP will be enabled on first launch after the IMSA server installation,
if it was not already enabled
If you configure high availability mode, configuring client-side SSL termination at the sprayer is recommended. In this case, there is no need to enable SSL for HTTP.
If you do not configure high availability mode, SSL must be enabled for HTTP; to validate that SSL is enabled, test that you can connect via web browser and HTTPS to your mail file (iNotes®), and log in successfully. Alternately, you could access the server at HTTPS://[host] to see the home page for the server, or a login page if the server does not allow anonymous access.
- For larger deployments IBM recommends increasing both the "Cached user expiration interval" and "Maximum cached users" values, which can be found in the server document ( ). Set "Cached user expiration interval" to 28800 seconds (8 hours); for "Maximum cached users", please set to the number of users that are expected to be using this IMSA server.
Server settings - user access
Note: The IMSA server does not support users in
multiple domains. Users added to IBM mail support for Microsoft Outlook must be in the same domain as the IMSA mail
server.
Each user who is accessing the IMSA server must have: - A mail replica on the IMSA server(s)
- A valid internet address, set in the user's person document
- A valid internet password, set in the user's person document (only required if you will be using Domino authentication)
- The user's Notes® ID must be in an ID Vault - if you are not currently using ID vault, set one up.
