Size Limits on SEAS Email

Our mail system has two types of storage. Your inbox can hold all the mail that you have received in the last 30 days, and 250 MB of mail older than 30 days. Your mail folders are limited only by the size of your SEAS home directory. Your inbox is separate from your SEAS home directory; it is additional space only for incoming mail.

There is no fixed limit on the amount of email that can be saved in your inbox, but if more than 250 MB of messages are saved for more than one month, the oldest messages will be moved to a separate mail folder in your SEAS home directory. Our mail server continues to accept mail messages when your mailbox is over 250 MB. We believe that this is preferable to the common practice of refusing incoming mail when an inbox "fills up".

Email Inbox Limits

The SEAS mail server has an inbox limit of 250 MB. Please note that your email inbox does not count against your SEAS home directory quota, and that the size of your other mail folders do not count against the 250 MB limit on your inbox.

Email Message Limits

On the SEAS mail server there is a limit of 20MB on incoming and outgoing mail messages. CETS believes this limit will allow large email messages, even those with figures or other attachments, while providing a "sanity check" to prevent our filesystems from filling up if someone sends some unreasonably large message. If you find that this limit is inconvenient for normal electronic communication, please let us know (contact CETS).

When sending large email messages, please check first with the recipient. Systems at Penn and elsewhere may not be able to handle messages as large as SEAS allows. A large message may inconvenience the recipient, or may even disrupt the entire receiving system. Also, when including attachments you should check that the recipient will be able to conveniently detach and read the document type you send. CETS recommends negotiating this before sending the message.

Understanding your disk quota

Other than your inbox, all of the folders in your home directory count against your disk quota. Here are a few examples of other files and folders you may have:
