MTA Access to the New Post Office: Mapped and UNC Links vs. TCP/IP Links
If a domain includes multiple post offices, the new post office will probably reside on different
server from where the domain is located. If you plan to use mapped or UNC links between the
domain and the new post office, the MTA requires the same access to the post office directory as it
requires to the domain directory.
Figure 11-8
MTA Access Using Mapped or UNC Links
To avoid these direct network access requirements between the MTA and a new post office, you can
use TCP/IP links between the domain and the new post office.
Figure 11-9
MTA Access Using TCP/IP Links
When using TCP/IP links, the MTA does not write message files into message queues in the post
office directory structure. Instead, the MTA communicates the information to the POA by way of
TCP/IP and then the POA uses its direct network access to write the information.
NetWare:
If the NetWare
®
POA needs direct network access to another NetWare server where the
post office is located, you must add the
/dn
switch or the
/user
and
/password
switches to
the POA startup file to provide authentication information. Username and password
information can also be provided in the Remote File Server Settings box of the Post Office
Settings page in ConsoleOne.
Linux:
If the Linux POA needs direct network access to another Linux server, you must mount the
file system where the post office is located before you start the Linux POA.
Windows:
If the Windows POA needs direct network access to another Windows server where the
post office is located, you must map a drive to the other server before you start the
Windows POA.
NetWare:
If the NetWare MTA needs direct network access to a new post office on another NetWare
server, you must add the
/dn
switch or the
/user
and
/password
switches to the MTA
startup file to provide authentication information.
Linux:
N/A. The Linux MTA requires TCP/IP links to the POA.
Windows:
If the Windows MTA needs direct network access to a new post office on another Windows
server, you must map a drive to the post office directory before you start the MTA.
