On UNIX, the existing SMTP server should be replaced by PMDF's SMTP server during the installation of PMDF; see the appropriate edition of the PMDF Installation Guide .
On NT, any existing SMTP server must be disabled, so that the PMDF SMTP server may replace it. For instance, Windows 2000 Server and Advanced Server do have a native SMTP server by default. To disable the Windows 2000 Server or Advanced Server native SMTP server:
On OpenVMS, your TCP/IP package's native SMTP server must be replaced by PMDF's SMTP server. First the native SMTP server must be disabled, as described below, then the PMDF Service Dispatcher must be configured to handle the SMTP service, as described in Section 23.1.4 , and then the Service Dispatcher must be restarted, or started if it was not already running, to start up the new service.
Disabling the DEC TCP/IP SMTP server, or a PMDF UTCP SMTP
server
To disable the SMTP server native to DEC TCP/IP Services, (also known as ULTRIX Connection or UCX), or a previous PMDF UTCP channel, issue the commands:
$ UCX UCX> DISABLE SERVICE SMTP UCX> SET NOSERVICE SMTP UCX> SET CONFIGURATION ENABLE NOSERVICE SMTP UCX> EXITIf your site was previously using the PMDF UCX_SMTPD dispatcher, you must also delete that process; it will have a process name of UCX/PMDF server. Also remove any command from your system startup that starts up that process; e.g., remove any commands such as
$ @PMDF_COM:start_ucx_smtpd.com
Disabling the TCPware SMTP server, or a PMDF PTCP SMTP
server
To disable the SMTP server native to Process Software TCPware TCP/IP, or a previous PMDF PTCP channel, issue the commands:
$ RUN TCPWARE:netcu NETCU REMOVE SERVICE 25 TCP NETCU EXITOr if you are running Process Software TCPware TCP/IP V5.3, you may disable the SMTP server using the interactive configuration tool,
$ @TCPWARE:CNFNET TCPby answering NO to the question regarding using the SMTP server, along the lines of:
Do you want to use the SMTP Mail Transfer Agent?
Note that if you have also installed Process Software's SMTP-VMS optional product, you must disable it by issuing the following command:
$ RENAME TCPWARE:smtp_control.com - _$ TCPWARE:smtp_control.com_disabled
Once you have disabled the SMTP server native to Process Software TCPware TCP/IP, or a previous PMDF PTCP channel, TCPware should then be shutdown and restarted with the commands:
$ @TCPWARE:shutnet.com $ @TCPWARE:startnet.comIf you have TCPware installed in a cluster environment you must restart TCPware on every node in the cluster to ensure that each node knows about the change.
Disabling the Multinet SMTP server, or a PMDF MTCP SMTP
server
To disable the SMTP server native to Process Software's MultiNet TCP/IP (formerly Cisco MultiNet TCP/IP, formerly TGV Multinet TCP/IP), issue the commands:
$ MULTINET CONFIGURE/SERVERS SERVER-CONFIG> DISABLE SMTP SERVER-CONFIG> RESTART SERVER-CONFIG> EXITIf you have MultiNet installed in a cluster environment you must restart MultiNet on every node in the cluster to ensure that each node knows about the change.
