The Access Page of the Web-based administrator allows you to specify which TCP/IP port addresses SLmail will use. Each available remote access option is assigned its own TCP/IP port number. This tab is also used to define the default settings for these access protocols.
User Default means that this will be the default setting for all new users created within SLmail.
Enabled is a global setting. If Enabled is unchecked, that option will not be available for any users whether or not it is selected for a specific user account.
Please see the section on User Account Options for more information on setting specific user options that differ from system defaults.
The Control Panel Applet Access tab is nearly identical to the Web-based Administration.
With recent changes to the way that top level DNS providers restrict the number of open ports you may need to reconfigure the UDP port that you use for DNS resolution. If you are using an external DNS Server (not installed on the same machine as SLmail) it is recommended that you use port 53 (ports 54-1024 are currently blocked by some top level DNS providers). If you have a DNS Server installed on the same machine as SLmail you will have conflict on port 53 so it is recommended that you use port 54 (or another open port other than 53).
Enter the appropriate port in the text box provided.
The Finger protocol allows users to query the status of a mailbox and to supply information about their accounts.
The No User field will allow you to specify a text file, which can contain a customized error message if a finger command is sent for a non-existent account on your server.
The Error File field will allow you to specify a text file, which can contain a customized error message if an improperly formatted finger command is sent to your server.
Note: When entering in the name of a text file you must also enter in the complete path for that file as well, such as c:\textfiles\finger-error.txt . This path is relative to the SLmail server and not the machine from which you are administering SLmail.
Forced Connection to TCP/IP port allows SLmail to initiate the sending of queued mail from a Smarthost when SLmail is in dialup mode. When enabled you must enter in a node name. This node name is the fully qualified name or IP address of the machine where SLmail needs to connect. More will be covered on this in the Dialup Connections section of this documentation.
The Forced Connection to TCP/IP Port option is disabled by default.
Note: This option does not have a selection for User Default since this is not an option that affects user accounts in any way.
SLmail is both an SMTP server and a POP3 server. If you would like to limit a user to employ only SMTP and be prohibited from using POP3, which is the client/server interface to Internet mail, you can turn off POP3 services by disabling this option. By default, POP3 Mailbox Access is enabled.
Remote Finger Notification is a frequently overlooked feature in SLmail. With the proper configuration, it can be used for paging users when new mail is received, triggering an automated process, and more.
Remote Finger Notification allows SLmail to call a remote site via the Finger Protocol with a query for a specified user. Whenever mail is received for an account within SLmail that is set to use this feature, it will "finger" the pre-specified address. This can be useful as a method to notify a client program that mail has arrived.
From remote sites (for example, when dialed-in over long distance) users may wish to only check whether they have mail on the server. The Remote Mail Checking Protocol allows for this functionality. In order for this to be fully functional, you must use a client, which supports this protocol on the user's machine.
As system administrator, you may change a user's password through the Web-based Administration. It is often more convenient for users to modify their own passwords directly from their client systems. If you wish to disallow remote password changing, you can do so by disabling this option. (Eudora is at present the only client that supports this protocol.) By default, this option is enabled.
The default SMTP port number is 25. This port is reserved almost exclusively for mail. SLmail must be able to use Port 25 for the SMTP port, except in a very few cases where there is a need to allow for the use of a gateway or access between a firewall and SLmail.
Note: Do not change SMTP Port 25 to any other port number, unless either your system administrator or Seattle Lab's Technical Support had directed you to do so. If you disable SMTP Port 25 you may stop receiving email.
Note: SMTP port does not have an option for User Default. This is because the SMTP port is global and is not directly related to user accounts.
