Form tabs
Use this form to configure your Internet setup. For most Internet configurations, this will be the only form you need to use.
General tab
Use this tab for basic Internet setup.
Primary domain name
Your server's domain name. In outgoing mail, this will be added to the names of local users and to remote names that do not have domain name specified. In the address user@centrinity.com, the domain name is centrinity.com.
Primary DNS
The IP address of your primary DNS server. If you do not maintain your own DNS server, obtain this address from your Internet Service Provider (ISP). If you have more than one DNS server, enter their addresses on the Advanced DNS form.
Postmaster name
All Internet email addressed to "postmaster" will be sent to this person. In most cases, this is the administrator.
Start Internet Services automatically
Starts Internet Services whenever you start your server. For this option to work:
• the Internet Services component of FirstClass must be installed on the same machine as the server component
• you have not changed the name of the Internet Services executable.
Connection tab
Use this tab to specify when Internet Services will connect to the Internet.
Internet connection
The type of Internet connection.
• Continuous
Select this if you have a full-time connection to the Internet. Outgoing mail will flow continuously and news and mail polling will be controlled by the Internet Service Account schedule that you specified on the Service Account form.
• Intermittent or dial-up
Select this if you do not have a continuous connection to the Internet. Specify the connection schedule on the Service Account form. You must also set routing information on the Advanced Mail form.
Note
Before configuring Internet Services for dialup connections, you should already have installed and appropriately configured dialup software on the computer on which Internet Services is installed (for example, FreePPP on Mac OS and Dial-Up Networking on Windows). You must also configure the system to recognize these. For more information, see your system documentation. You must set a low timeout value when you configure this software. The Scheduling tab of the Service Account form controls when you dial into your Internet Service Provider (ISP). The timeout value of your dialup software is how you control when the connection is dropped.
Routing button
Opens the Routing tab of the Advanced Mail form. Set routing information for outbound mail there, if you selected "Intermittent or dial-up".
Schedule button
Opens the Scheduling tab of the Service Account form. Set scheduling information there, if you selected "Intermittent or dial-up".
Mail tab
Use this tab to set up Internet mail.
Enable SMTP
Allows FirstClass to make connections to and receive connections from other SMTP servers, to transfer Internet mail.
SMTP server domain name
The domain name for your SMTP server. Normally, this will be in a format like mail.centrinity.com. This name must be defined on your DNS server and must point to the IP address of the machine on which Internet Services is installed.
For each protocol you enable in Basic Internet Setup that requires a server domain name, we recommend that you provide a separate server domain name, even if all these names point to the same server machine.
Enable POP3
Allows users of POP3 mail clients on the Internet to connect to Internet Services to retrieve their mail. All they have to do is point their POP3 client at your mail domain. You must enable this to allow users to retrieve mail using POP3 from an Internet Service Provider (ISP) mailbox as defined on users' information forms.
Enable IMAP4
Allows users of IMAP4 mail clients on the Internet to connect to Internet Services to retrieve their mail.
Max outgoing mail
The maximum number of messages you want to send simultaneously. Normally, you will accept the default 10. Increasing this number will require more memory.
Mail server
The name of the server you connect to in order to retrieve mail if you use POP3 message importing (for example, mail.myISP.com). This is normally your Internet Service Provider's mail server. This server will be used unless another one is specified on a user's information form.
Advanced button
Opens the Advanced Mail form. You will not need to use this form unless you have an unusual Internet setup.
News tab
Use this tab to set up Usenet news.
Enable NNTP
Provides for message transfer to and from Internet newsgroups by enabling the NNTP client protocol on your server.
NNTP server domain name
The domain name you want associated with the NNTP protocol (for example, news.centrinity.com). This name must be defined on your DNS server and must point to the IP address of the machine on which Internet Services is installed.
For each protocol you enable in Basic Internet Setup that requires a server domain name, we recommend that you provide a separate server domain name, even if all these names point to the same server machine.
NNTP feed server
The name of the server that provides your news feed. This is where newsgroup posts created on your system are sent. In most cases, this is your Internet Service Provider's news server.
Advanced button
Opens the Advanced News form. You will not need to use this form unless you have an unusual Internet setup.
Web & FTP tab
Use this tab to set up the HTTP and FTP protocols. HTTP lets you publish material on the web. FTP lets you make documents available for download.
Enable HTTP
Lets you publish HTML documents from your web server by enabling the HTTP protocol on your server.
HTTP server domain name
The domain name you want associated with your web server. This name must be defined on your DNS server and must point to the IP address of the machine on which Internet Services is installed.
Enable FTP
Allows users to download files from your server and from users' home pages with an FTP client by enabling the FTP protocol on your server.
To make files available for FTP, place them in the Internet Services\FTP folder.
FTP server domain name
The domain name you want associated with your FTP server. This name must resolve to your FTP server machine, be defined on your DNS server, and point to the IP address of the machine on which Internet Services is installed.
For each protocol you enable in Basic Internet Setup that requires a server domain name, we recommend that you provide a separate server domain name, even if all these names point to the same server machine.
Multiple Sites button
Opens the Multiple Sites & Languages form. Use this form if you need to create multiple web sites, or multiple languages on one web site.
Advanced button
Opens the Advanced Web & FTP form. You will not need to use this form unless you have an unusual Internet setup.
Directory tab
Use this tab to give users with Finger and LDAP clients access to your FirstClass Directory.
Enable Finger
Allows Internet users to search the Directory using a Finger client by enabling the Finger protocol on your server.
Enable LDAP
Allows Internet users to search the Directory using an LDAP client by enabling the LDAP protocol on your server.
Advanced button
Opens the Advanced Directory form. You will not need to use this form unless you have an unusual Internet setup.
UCE/Spam tab
Use this tab to configure relaying and junk mail rules. You can control which messages your site will relay (forward to an address not served by your system), which messages to accept, and how to handle these messages based on your choices.
Relaying
How you want your server to relay messages:
• Disable ALL relaying, including SMTP AUTH and trusted IPs
Disallows all relaying off your system. This does not affect users sending email with FirstClass client software.
If you allow relaying, you can limit it to people with certain features and user preferences.
Note
Preferences are set in a user's profile on the User Information Form.
Handling junk mail
How you want your server to handle junk mail.
• Reject unknown domain names
Rejects all messages from IP addresses unknown to your server.
• Reject based on RBL hosts(s)
Disallows connections from any IP addresses listed in your RBL server.
RBL host name fields contain the names of RBL service you use.
Note
There are several Real Blackhole List (RBL) services you can use with varying degrees of aggressive IP lists. We recommend you choose one or two good RBL services that are not too aggressive in their IP lists. For more information on configuring a RBL setup, see FirstClass Internet Services Administrator's Guide.
Help text fields contain messages the sender receives that describes why the connection was refused and contains a link to the RBL site where corrective action can be taken. You will only have one message per RBL site.
An example of this is, "Your mail has been found on our RBL service list and will not be delivered. Go to rbl.spamcop.org for more information".
• X-RBL-Warning header instead of NDN
If unchecked, sends 550 followed by information in Help text (see Help text).
If checked, a warning goes to the recipient in the header of the message informing him that the sender's IP address has been found on a RBL service list. The recipient should implement personal mail rules (see online help) to handle future emails from sender.
NNTP crossposting limit
The maximum number of crossposts (single news items posted to multiple newsgroups) that will cause news to be rejected. FirstClass rejects any newsgroup messages with more crosspostings than this limit. For example, if you select 10, a news item crossposted to 10 newsgroups will be accepted, but one crossposted to 11 newsgroups will be rejected.
It is generally considered bad netiquette to crosspost to more than two or three newsgroups. Excessive crossposting is often used to distribute junk mail. By specifying a low number, you will probably eliminate a considerable amount of junk mail.
Service tab
Use this tab to set up the basics of your Internet account and the priority level at which the Internet Services executable will run.
Service account
The account to which automatched addresses are linked. If a message has an address containing @, FirstClass sends the message for delivery to the Internet account. This is also the account that Internet Services uses for mail and news routings and for public (nonauthenticated) access through HTTP, FTP, Finger, and LDAP. There must be a service with this name in the Gateways folder.
The default name is Internet. Do not change this default unless you reconfigure the Internet account and change the name. Do not change this to the name of a third party gateway.
Internet Services priority
The priority of Internet Services operations on this machine:
• High
Select this if Internet Services is running on a dedicated machine or on a system with multiple CPUs.
• Medium
Select this if the server and Internet Services are running on the same machine.
• Low
Select this to allow other software to run on this machine with little performance impact. Only do this temporarily, because Internet Services' performance will be severely affected.
We recommend against running software other than the server and Internet Services on the same machine.
Internet sessions
The maximum number of incoming Internet protocol connections (for example, Finger, POP3, HTTP) that Internet Services will accept. A single session can generate more than one connection. For example, someone accessing your web site with HTTP may establish several connections at once, separately downloading the text and various graphics on your page.
Check the Internet Monitor to see whether the number of sessions you have set here is appropriate, or whether connections are being rejected.
Configure button
Opens the Service Account form. Use this form to view or update the Internet service settings for this account.
