The Mail server will be monitored by a Tullnet Internet host once every 10 minutes. If the server is uncontactable for longer than a user-specified time, then the independent host will send an SMS alert to a user-specified mobile telephone number.

The Tullnet monitoring host will receive load data from the customer mail server and will send an SMS alert if any of the following defined situations occur:

• Excessive CPU load
• Disk free space less than required
• Connectivity problems

The SMS network does not guarantee delivery of SMS messages to the end user.

The end user must provide details of their email requirements at purchase time, including:

• Names and contents of own domains
• Required usernames

Any redelegation of domains required by the customer will incur an additional fee (P.O.A.)

System configuration does not include any modification to the customer's existing PCs on the LAN. LAN PCs must be modified to use the new mail server address for sending messages and picking up email.

The mail server is designed to be used within a firewall, but the firewall must permit email from outside to be delivered to the mail server. Firewall configuration will be undertaken at the customer's expense unless the firewall server is the Tullnet Firewall and Proxy Server.

The customer is responsible for providing a 100 mbit switch to connect the mail server to its Internet gateway.

This option is included with the first 12 months of every mail server bought from Tullnet Pty Ltd.

Tullnet monitors Internet security alerts and reacts to protect your mail server in any situations in which the mail server appears to be vulnerable.

The mail server software is upgraded for non-critical security fixes and other improvements on a monthly basis (as updated packages are available).

The web-based management system is password-protected and is available to both the end-user and Tullnet Pty Ltd. Incorrect reconfiguration of the server using this interface can prevent it from working. Tullnet Pty Ltd will charge a call-out fee if a site visit is necessary in order to repair a damaged server.

The Next Business Day replacement option is designed to provide a quick recovery for a business when a mail server suffers a hardware failure.

In the case of "server down" a Tullnet technician will visit onsite with a replacement server. If the cause is determined to be a software failure then the only fee payable will be a call-out fee. If the cause is hardware failure then the technician will swap in a replacement server which will then become the property of the customer. Ownership of the failed server will revert to Tullnet Pty Ltd.

The customer is responsible for backing-up the contents of all email stored on the mail server.

The server replacement option is intended to cover situations only where a warranty replacement would apply. It does not cover mistreatment of the hardware, accidents or failure due to electrical interruptions, lightning strike or other environmental causes. In these non-covered situations the Tullnet technician will advise the customer that a swap replacement is not available and offer to sell a replacement server to the customer at a discount. If the customer accepts the offer then the replacement server will be swapped for the failed server, the ownership of the replacement server will transfer to the customer and the ownership of the failed server will revert to Tullnet Pty Ltd.

The Next Business Day replacement option is limited to a maximum of 2 server swaps per 12-month period. Any hardware failure in excess of this limit will require the customer to purchase a replacement server in accordance with the previous paragraph.

Prices are quoted inclusive of GST. However Tullnet Pty Ltd is not registered for GST at this time and so tax invoices will be supplied with a $0 GST component until Tullnet Pty Ltd registers for GST.
