7.3.1 Before You Configure MMP

Before configuring the MMP:

1. Choose the machine on which you will configure the MMP. It is best to use a dedicated machine set aside for the MMP.

   ---

   Note –

   It is recommended that the MMP not be enabled on a machine that is also running either the POP or IMAP servers.

   If you install MMP on the same machine as Messaging Server, you must make sure that the POP and IMAP servers are set to non-standard ports. That way, the MMP and Messaging Server ports will not conflict with one another.

   ---

2. On the machine that the MMP is to be configured, create a UNIX system user to be used by the MMP. This new user must belong to a UNIX system group. See 1.1 Creating UNIX System Users and Groups

3. Set up the Directory Server and its host machine for use with Messaging Server, if they are not already set up. See 1.2 To Prepare Directory Server for Messaging Server Configuration

4. If the MMP is upgraded before the backend servers, customers should set the Capability option in ImapProxyAService.cfg to match the response to the capability command from the older backend. This would be:

   IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS CHILDREN LANGUAGE XSENDER X-NETSCAPE XSERVERINFO

   Note that line break is for editorial clarity, and that the configuration value must be on one line.
