Having MailSite Coexist with ListManager

The way to have MailSite coexist with ListManager is to have MailSite listen to another port besides port 25 (the SMTP mail default port). Let ListManager listen on port 25, then tell to forward mail on to MailSite.

Here are the steps to have MailSite and ListManager coexist:

Move MailSite to another port

* Use the registry editor (regedt32.exe) to move MailSite to port 26. The key you want to create is located HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SMTPRS\Parameters

This key holds certain configuration information relating exclusively to the SMTPRS service. (Please note that your version of the product may use a different name for the SMTPRS service, such as SMTPRA.)

You should create a new value (use "Edit/Add Value" menu) with a Value Name of "PortNo", a Data Type of REG_DWORD, and a Data of "26" (be sure to choose Radix: "Decimal").

* Restart MailSite.

Install and Configure ListManager

* Create an 'A' record in your DNS, which is an alternate name for the current machine. The mail that should be accepted by ListManager will be sent to this address. All mail delivered to ListManager which does not have this name will be forwarded by on to MailSite.

For example, if your machine is currently called "mail" in your DNS, add another entry below it that has the same data, but with a new name, as in:

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

After this change, restart your DNS server.

* Start your ListManager server in the foreground, by clicking the "Run ListManager Now" icon.

* In Utilities: Administration: Server: Server Settings: Network Settings: Receive Email, find the field that says "Forward Mail:". Type this in the Forward Mail field:

127.0.0.1 26

This instructs ListManager to forward non-ListManager mail to port 26, where MailSite is listening.

Now, find the field named "Mail Receive Rules" in Utilities: Administration: Server: Server Settings: Security: Bans. Type the name (or names) of the host names that ListManager should accept mail for. Any mail that comes in for ListManager, which is not addressed, to these hosts will automatically be forwarded to MailSite.

For example, if your machine was called "mail.mycorp.com" and you made an alias for it (in step 2) called "listmanager.mycorp.com", then in the "Mail Receive Rules" field enter this data:

@listmanager.mycorp.com

If you have multiple names for your ListManager server, which ListManager should answer, enter each of them here, separated by a carriage return. This means that all mail addressed to "@listmanager.mycorp.com" will be accepted and processed by ListManager, and any mail not addressed to "@listmanager.mycorp.com" will be forwarded to MailSite.

* Press "Ctrl-C" on your ListManager server console. Wait for ListManager to shutdown, then start it again, by clicking the "Run ListManager Now" icon.

* Start your mail program and send mail to lm@ your host name. For example, if your ListManager alias is "listmanager.mycorp.com", send mail to "lyris@listmanager.mycorp.com". A minute or two after sending your message, ListManager should have sent you a response back. Now, send a test message to a user on your MailSite Server to make sure that is working.

You are done!
