Computer newbies: Are e-mail addresses case sensitive?
Are e-mail addresses case sensitive?
by Vince.Rosati - 10/29/09 5:20 PMI maintain directories of members for a society. Whenever I add a name or have to modify an existing address, I like to capiatalize as appropriate, because I think that that makes the address more readable and less prone to typing error.
For example instead iv vincerosati@aol.com I would show the address as VinceRosati@EEDept.Purdue.Edu I am told that there are some systems that will not recognize a capitalized address, only addrsses that are all lower case.
Is this true?
No, they are not (at least what I've used)
by itsols - 10/29/09 8:59 PM In reply to: Are e-mail addresses case sensitive? by Vince.Rosati(To my knowledge and experience) email addresses are NOT case sensitive. But if your web host is APACHE, you'll definitely notice that FOLDERS and FILE NAMES are CASE SENSITIVE.
Happy computing!

Thanks for the reply. I have also never exerienced a problem, but one of the people in my group insists that they are.
I'm going to continue with capitalization.

The domain part of the address (the part after the @ is not case sensitive) but the user ID part (the part BEFORE the @ IS case sensitive.. But generally, it doesn't matter which case it's typed in primarily because it's not enforced by most ISP's.. Confusing, I understand ..No need to retype it here. See the information in the link below:

Hope this helps.

Case-sensitive email addresses

Thanks (again) Grif.
The articles seem to say that if an ISP or mail client does not recognize the capitalized address, then an error message would be returned. So, I guess I haven't caused too many problems because I would have heard about it.
But I guess that from now on I should stick to lower case, (Too bad, I think. The readability of addresses just seems to be so much better with capitalization.)
C'est la vie.

Vince

email addresses
by zepper - 10/30/09 6:47 PM In reply to: Are e-mail addresses case sensitive? by Vince.RosatiI rarely find that email servers enforce caps strictly, but some URLs can be case sensitive. In this: http://www.dell.com/foLder the part up to the / after .com is not strict, but the part after the / can be, as it can stand for a folder name in the Unix file system, where case is enforced. So, I don't think I ever use caps in mail addresses, but I do in URLs. I don't recall ever having a problem with that.

YES!!! And often also, no
by DougSK - 10/30/09 10:17 PM In reply to: Are e-mail addresses case sensitive? by Vince.RosatiEmail addresses ARE case-sensitive, if the system on which they were generated is case-sensitive. This USUALLY means email addresses from UNIX systems. Most email addresses these days come from web-based or Windows-based servers and services and are therefore not case-sensitive.
However, since it is impossible to definitively determine what system the email address came from, it is best to always use the email address EXACTLY as you receive it.
OTOH, if you wish to ignore that advice, then at least watch out for email addresses in .gov and .edu domains as they are some of the ones most likely to be case-sensitive.
Case Sensitivity
by jcbowen - 10/31/09 5:30 AM In reply to: Are e-mail addresses case sensitive? by Vince.RosatiAs others have stated, the part of the address after the @ is technically case sensitive, although this is virtually always ignored by mail servers.
However, the part of the address before the @ is NOT case sensitive. So for my address: jimbowen@domain.com I always use JimBowen@domain.com because of the improved readability/recognizability it provides.

capital system?
by tlworkroom - 10/31/09 8:40 AM In reply to: Are e-mail addresses case sensitive? by Vince.RosatiIn the early days of popularized email, yes, it was incredibly important to be correctly capitalized or not. Oh, it was such a high security risk that to prevent unauthorized access, they used capitalization to afford just one more way to hopefully keep the bad guys out.
But as time progressed, most people and companies realized that using capitals in email was time consuming and needless. So thankfully, most of the world has forgotten that old antiquated effort of internet security.
There may be some instances where capitals are still required. But mostly the world has moved on beyond that performance that is "soooo 90's!!"
Capitalization in email address

yes adresses are case sensitive
by cboardwoman - 11/1/09 2:05 PM In reply to: Are e-mail addresses case sensitive? by Vince.Rosatifrom my experience with computers over 35 years e-mail addresses as well as passwords are care- sensitive. as well i know that computers have a harder time processing caps over smalls(i call them). a lot of programs will reject caps as invalid characters .so my suggestion would be to create screennames in smalls unless asked to do in caps. this reply is only from my experience and you do not have to take my input as truth thanks
YES, email addresses CAN be case sensitive
by ruggb - 11/1/09 6:51 PM In reply to: Are e-mail addresses case sensitive? by Vince.RosatiAfter years of telling people that case did not matter I ran into an Web address that was listed with a note that it was case sensitive. I went to Wikipedia and found that the standard for URLs and emails does indeed allow for case sensitive email addresses thought it discourages it.
I then tried the address without the case and it did not work until I capitalized the indicated letters.
MOST capitalization is for looks. Most people think it is required. FACT is, only a very few addresses require it, probably because the author did not fully read the part that said, though you can it is best not to.
