BlitzMail
BlitzMail was an e-mail system used at Dartmouth College in Hanover, New Hampshire, United States. It was one of the earliest e-mail server/client packages. It became instantly popular at the college as a result of its simplicity and power, appealing to even the most inexperienced users. To the dismay of many students and alumni of the College, use of BlitzMail ended in 2011, in favor of a Microsoft suite of email/online collaboration programs. The Dartmouth Name Directory will allegedly live on, however, and the new e-mail program is still referred to as "Blitz."
