UIUC Mathematics Email Migration - Mailbox Size
Moving email servers from Math to campus will not limit your mailbox size.
Q. I have a lot of email. Will the server be able to handle it?
A. The campus email server has over a petabyte of disk storage; for
comparison purposes 10 Terabytes can contain the printed collection of
the US Library of Congress. There is no hard limit on disk space so
you will not get the annoying 90% disk space left message. Another
nice feature is that when you get close to the limit the campus email
server will automatically resize your mailbox.
