1. It is our goal to move all our users from their existing mail systems to a single system that provides IMAP and Web-based access to the message store. User mail migration from the old systems to the new system is NOT a requirement of this RFP. Such migration will be handled internally.

2. Each user will receive an initial 20-MB quota for e-mail storage. The e-mail system must manage this quota automatically. The storage system must be expandable from the initial 200 GB to 1 TB for anticipated future growth in storage requirements.

3. The new system must support controls for reducing the delivery of spam to internal users. The system also must provide safeguards against use as a potential relay host for spam.

4. Current usage patterns indicate that an average of 40 percent of our users are connected to their mail system during the peak hours--between 8-5 on weekdays. We anticipate that 80 percent of these users will use an IMAP client on a regular basis and 20 percent will use a Web interface. Both classes of users require access to a systemwide address book for address searches and address block completion

5. Web access authentication via SSL and encrypted IMAP authentication is required. The mail server and supporting infrastructure will sit behind the corporate firewall. IMAP and Web access into the system needs to be accessible from anywhere on the Internet.

6. The mail system must meet or exceed 99.9 percent uptime requirements. Fault-tolerance should be designed into the system at both the server and the storage subsystem.

7. Systems designed with a clear strategy for traffic growth, storage capacity increases and fault-tolerance will be viewed favorably.

Requirements for NetMagik's 250,000-User E-Mail Infrastructure

1. It is our goal to move all our users from our existing mail system to a more scalable system that provides a tiered service with POP-based messaging for the lower tier, approximately 60 percent of our users, and IMAP and Web-based access for the 40 percent in the upper tier. User mail migration from the old system to the new system is NOT a requirement of this RFP. Such migration will be handled internally.

2. POP users will receive a 2-MB quota for incoming e-mail storage. The upper-tier IMAP users will receive an initial quota of 5 MB of mail storage with additional storage available for a fee. The e-mail system must manage these quotas automatically and provide an interface to our billing system for accurate charges. Based on the size of our existing message store and anticipated growth because of the IMAP offering, we require 1 TB of storage initially.

3. The new system must support controls for reducing the delivery of spam to internal users. The system also must provide safeguards against use as a potential relay host for spam.

4. Current usage patterns indicate that an average of 5 percent of our users are concurrently connected to the mail system during our peak hours. We anticipate the same 60/40 split for users connected via POP and IMAP respectively. Both classes of users require access to a systemwide, LDAP-based address book.

5. Web access authentication via SSL and encrypted IMAP authentication is required.

6. The mail system must meet or exceed 99.99 percent uptime requirements.

7. Systems designed with a clear strategy for traffic growth, storage capacity increases and fault-tolerance will be viewed favorably.
