The table below summarizes the various combinations of the platform of MTA for the source
domain and the platform where the destination domain is located, and indicates which combinations
work for direct access and which ones do not:
Table 40-2
MTA Platforms and Domain Platforms
1
TCP/IP links are required between MTAs in GroupWise 7. Direct access to other domains is not
available.
2
The NetWare MTA cannot write message files into its output queue in a destination domain on a
Windows server because Windows does not support the required cross-platform connection.
3
Domains cannot be created on Macintosh computers.
40.7.4 MTA/Domain Platform Independence through TCP/IP
Links
To overcome platform dependencies between domains, use TCP/IP links between domains. See
Section , “Using TCP/IP Links between Domains,” on page 618
.
40.7.5 MTA/Domain Platform Independence through the
Transfer Pull Configuration
If TCP/IP is not available, another alternative for overcoming platform dependencies is a transfer
pull configuration.
By default the MTA “pushes” message files out to destination domains by writing them into its
output queue in each destination domain. One situation where this method does not work is for the
NetWare MTA on a NetWare server to write message files to its input queue in a destination domain
located on a Windows server.
As an alternative, you can have the Windows MTA for the destination domain “pull” the message
files from the source domain on the NetWare server. This is called a transfer pull configuration. See
Section 41.3.3, “Using a Transfer Pull Configuration,” on page 636
for setup instructions.
