Nope. By convention, email addresses are not case sensitive. Making
them case sensitive would break user expectations and create enormous
amounts of pointless frustration.

[Discuss] MIT usernames (was Re: KVM, virt-manager, and CentOS7)
Not quite sure how a discussion of KVM veered off into MIT auth procedures, but it did give me a bit of nostalgia. My shortest (and first) email address was rkb@ai (DNS became the new-new thing a couple years later). Then for a decade or so I was ri...@mit.edu until my Athena sponsor headed off to the corporate world. Another fond memory of those early days is the domain spdcc.com. I guess now the most concise I could do is r...@ci.net but for no good reason other than inertia I've kept the same lengthy address for the past 24 years. Do you have a favorite email address, past or present? -rich ___ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss

The real problem is the lack of human meaning and the fact that names are usually longer than 8 characters. How many do they assign a year? Roughly a freshman class worth, plus maybe a hundred more? So 1200ish. John Smith is out of luck. So is Elizabeth Jones. But still, they probably have better options than "bb30...@binghamton.edu" -- the login I was assigned so many years go, can still remember, and have absolutely no use for. -dsr- ___ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss

Generally @mit.edu addresses are "recovered" approximately 1-2 years after they leave MIT. There are exceptions for certain classes of people whose accounts remain "sponsored". It's unclear what happens if a sponsored account owner passes. Then there are "alum.mit.edu" accounts, which is MIT's "Email Forwarding for Life", which allows more than 8 characters, so there's really no issue. -derek > > >> Dan Ritter writes: >> >>> On Wed, Feb 08, 2017 at 10:24:54AM -0500, Derek Atkins wrote: Eric Chadbourne writes: > Off topic, warl...@mit.edu, is the best email ever.

Re: [Discuss] KVM, virt-manager, and CentOS7
Here's the problem with all this. 8 characters for a name. Yes, in a hypothetical sense you have 2.183401056×10^14 possible passwords if you use 8 ascii alpha/numeric characters with no punctuation characters, but the vast majority of that space are random strings not suitable for nicknames or meaningful identifiers. For instance, I can't see that any remaining meaningful permutations of "john smith" could possibly be left. How many email addresses do they assign a year? How many back-logged names did they create at first?
