Having Post.Office Coexist With ListManager

Post.Office is capable of peacefully coexisting with ListManager on the same machine without any problems. The following instructions explain how to set this up. The process involves making a second name for your computer, moving ListManager to another TCP/IP port and telling Post.Office to forward mail sent to that second name on to ListManager.

Here are the steps:

1) Create up an alias for your computer by adding an additional "A record" to your DNS entries. For example, if your machine is named "po.yourcompany.com", copy the "A" record entry for that host, make a copy and change the name in the copy. Your DNS entry would look like this:

po IN A 207.105.6.2 ; the original host name
listmanager IN A 207.105.6.2 ; the new "alias" host name

2) Tell ListManager what port you want it to use. In this example, we are using port 26. To do this, open up a command window, change to the ListManager directory and type:

lm smtpport 26

3) Connect to Post.Office web page, log in as postmaster.

4) Click on 'System Config' button.

5) Click on 'Set Mail Routing Options' button.

6) Under "Special Routing Instructions - SMTP Mail Routing Table:"

Type:

name_of_listmanager_site:name_of_mail_server#port_number

For example, if your Post.Office machine is named "po.yourcompany.com" and the new second name, the "alias" is "listmanager.yourcompany.com", you would type::

listmanager.yourcompany.com:po.yourcompany.com#26

7) Now, start up your ListManager.

8) You're ready to go. When you create your "sites" be sure to use the new hostname in the "hostname" entry. In this example, this is "lm.yourcompany.com".
