This type of transport provides an Ethernet-based method for transferring messages with a PC-based SPX client program. This type of transport communicates directly with the cc:Mail client for message transfer. You must specify the following parameters:
|
|
Server Name: The name of the SPX server for this channel. |
|
|
Client Name: The SPX name of the PC. |
|
|
Server Address: The hexadecimal socket number used by the SPX service. |
This type of transport moves messages between the UNIX operating system and the PC running a client through a shared file system available to both platforms. When a channel is configured to use file sharing transport, you must specify the shared directory to use for the file exchange.This directory must be accessible for read and write by the cc:Mail client PC using file sharing.
Note - The cc:Mail client returns a nondelivery report for all recipients, even valid ones, if there are one or more bad recipients. If you receive a nondelivery report when sending mail from an SMTP/MIME user to a cc:Mail user, the nondelivery reason for the good recipients is "unknown," and a diagnostic code is not indicated.
Subdirectories are created as needed beneath this shared directory by the SIMS administrator. The cc:Mail channel uses two directories beneath the selected directory, /in and /out, to exchange messages with the cc:Mail client.
The Admin Console will create directories and set permissions correctly so you do not have to manually set them.File sharing requires that both the channel and the PC client have read, write, and delete privileges in the shared directories. The channel is owned by root, but executes as inetmail.
In UNIX system terms these privileges are equivalent to a permissions set of 660, where the user ID that owns the file (either the channel or the PC client) has read, write, and execute privileges for the file, and the inetmail group (either the channel, the PC client, or the channel or site administrator) has read, write, and execute privileges on the file. These permissions limit file access to only the channel, the PC client, and the site and channel administrators, preserving the security of the messages in transit.

Configuring the Transport for SPX |
The SPX Transport program listens for connections from a PC client program; connections are always established by a "call" from the PC client. The client establishes an active connection to the SPX Transport program. The programs then exchange any queued messages and attachments, deleting the local copies after successful delivery to the corresponding directories on the other system. When all messages are transferred, the client program drops the SPX connection.
| 1. | Type the server name in the Server name text box. This parameter can contain from one to eight alphanumeric characters, and must match the SPX server name provided on the PC side of the link. |
The default value for this parameter is SPXSRV. Any or all channels can use the same server name, so you should not need to change this parameter.
| 2. | Type the client name in the Client name text box.This parameter can contain from one to eight alphanumeric characters, and must match the client name on the PC side of the link. |
| The default value for this parameter is CCMAICLI. This name must be unique within your configuration, so choose another name (such as CCMAICL2) if you have more than one cc:Mail channel. |
| 3. | Type the server address in the Server address text box. |
| The default SPX socket number is 8000; valid ranges are 0001-0BB8 and 8000-FFFF. In almost all circumstances, the default will suffice. In rare cases, other software on the Ethernet may be using SPX socket 8000, in which case you should choose another value. If you change the server address from the default, you must also specify the new socket number using the SERVERSOCKETADDRESS parameter in the client configuration. |
If Sun's NWServ is installed, opt/SUNWefps/sbin/ipxstat-i will show the address for SunNet PC. If TotalNet Advanced Server is installed, /opt/totalbin/bin/tnistat -i will show you the address.

Configuring the Transport for File Sharing |
Enter the name of the directory to be used for the file exchange between the server and the PC client. The cc:Mail client allows one to eight characters for filenames and directory names.
Directory synchronization (dirsync) is the process by which directories that operate independently of each other are updated so the information within them is consistent. Dirsync ensures that when a change is made in one directory, corresponding directories are updated as well.Refer to the Sun Internet Mail Administrator's Guide for additional information on dirsync.
