Manage Your Mail

How big is your US Mail mailbox at home? What would happen if you read your mail, but returned it to your mailbox? It would get increasingly stuffed and tax the ingenuity of your mail carrier until one day there would be no way to bring you your mail. If you got a bigger mailbox, you would only delay the problem.

Electronic mail suffers from the same limitations. There is only so much disk space allocated to your inbox, and a message that won’t fit will be returned to sender. So, unless you delete or choose some other place to store mail you’ve read (“refiling”), first large messages and then even small messages can’t be delivered to you.

Even with the best management, some faculty receive large attachments, and only a few of them are sufficient to strain email capacity. NACS is piloting a Web-based file sharing system that will provide a means of collaborating on large files superior to using attachments.

Enterprise Services

NACS has made a number of changes to central services to better meet client needs.

Disk capacity for EA and E4E has been expanded. Users have two separate storage areas: one which provides temporary storage for incoming mail (“inbox”), and the other, with substantially greater capacity, is for long term storage of mail messages, attachments, and any other files (“home directory”).

Undergraduate students are allocated 3MB of inbox space and 8MB of home directory space. Graduate students are allocated 10MB of inbox space and 20MB of home directory space.

Staff and faculty are expected to keep their inbox usage to 10MB, but can continue to receive new mail until the inbox reaches 30MB. Inbox space is limited, and users are advised to download their incoming mail (for POP users) or to refile it to other folders (for IMAP users.) Users who compromise others’ ability to use e-mail by sustained use beyond the 10MB inbox limit are subject to losing the 30MB temporary storage privilege. NACS staff are available to assist users with inbox management.

Regular attention to one’s inbox is recommended, since the main campus e-mail server has been upgraded to allow attachments as large as 10MB. While this change was made as a service to faculty collaborating with off-campus colleagues, it does mean that even a 30MB inbox can fill quickly.

Staff are allocated 20MB of home directory space (but may use up to 50MB on a temporary basis), while academic senate faculty may use up to 100MB of home directory space. Users may review their disk usage and quota at (click on “Quota Check” and authenticate with your UCInetID and password.)

Additional home directory space, if needed, is available for $5/month for each 100MB. Disk space in E4E is high-performance, fault-tolerant, and includes backup and security services. Users whose priority is economy are encouraged to purchase local disk for their desktops and keep their large files there.
