  You need to configure the Internet Services connection schedule, on the Internet gateway form, to specify when your service will automatically connect to your Internet Service Provider (ISP). You can do this by:
• logging in as the administrator and opening the Internet gateway form in the Gateways & Services folder on the administrator’s Desktop
• clicking Configure on the Service tab on the Basic Internet Setup form.
Setting the Scheduling tab
The Time A and Time B subtabs control incoming email (POP3), news (NNTP), and dial-up connectivity. The Demand tab on the Gateway Settings form controls when the service will connect based on the number of incoming emails queued or when the user logs in (depending on what you choose).
This is how we set the schedule on Husky Planes:
 Since Husky Planes does business 24 hours a day, 7 days a week, we want to receive Internet email from our ISP using POP3 everyday. We chose a 4:00 am start time so email will be there for early risers and a 1:00 am stop time for trash collection and administrative tasks when usage would probably be low. Between 1:00 AM and 4:00 AM no email or news is retrieved.
We chose to connect between the start and stop times every hour. If users find they are waiting too long for information, you can increase the interval to repeat the connection. Of course, if there is a great deal of email and news, the individual connections will be long.
On Husky Planes, we don’t need to use the Time B subtab. The Time B subtab performs the same function as the Time A subtab but provides you with more flexibility when setting up your schedule. For example, if you have a connection where you are charged by time, or you don’t want to frequently retrieve email and news during off hours (for example, if you have a continuous connection but don’t want to put extra pressure on your system’s broadband capacity).
Setting the Demand subtab
On Husky Planes, we decided to retrieve messages and deliver them to users when they connect (or on the hour as set on the Time A subtab). This setting lightens the load on our server, as the messages are stored on the delivering mail server until the user is logged in (or on the hour as set on the Time A subtab). This means Husky Planes will retrieve messages every hour or if a user logs in during that hour.
 Configuring a dial-up connection
Husky Planes has a continuous connection to the Internet. However, if your organization uses a dial-up connection (you dial into an Internet Service Provider to send and retrieve email and news) rather than a continuous connection to the Internet, you must configure a dial-up connection. We will cover a basic dial-up setup here.
To configure a dial-up connection:
1 Select "Intermittent or dialup" on the General tab on the Basic Internet Setup form.
2 Select "Route through one server", on the Routing tab on the Advanced Mail form, and enter the IP address for that server.
3 Install and configure dial-up software on the same computer where you have Internet Services installed.
Note
Configure Dial-Up Networking on Windows or a third-party software router (such as the Vicom Internet Gateway) to handle routing of network and IP traffic for dial-up connection support on Mac OS X.
4 Set a low time-out value on your dial-up software.
5 Enter the information on the Scheduling tab and complete the Demand tab.
This forces a dialup connection, based on the number of queued messages for outgoing mail (SMTP).
Note
You can also use the Demand tab for continuous connections.
The schedule you set on the Scheduling tab controls when you connect. The low time-out value you set on your dial-up software controls when that connection is dropped. If you have a set rate for peak hours you can set the Time A subtab for frequent polling (for example, every five minutes). During off hours, where you are charged higher rates, you can set the Time B subtab for less frequent polling (for example, every two hours).
You should configure your Demand tab according to how many messages you want queued before initiating an automatic dial-up connection. For example, if you want all urgent messages sent out immediately, set Urgent Messages to a lower number. If you don’t require all your messages to go out immediately, set All messages to a higher number.
