For years I have believed that email addresses are not case
sensitive. I now wonder if that is true. I received a
"change of email address" message from a friend that read
something like my new email address is
and if I use the reply button with his message my message
gets to him. If, however, I enter the address as
the message bounces, saying there is no
such party at the ISP.

Enlightenment please.

Thanks.

As far as OE is concerned, addresses are not case sensitive. I would find it
hard to believe that it is an AOL thing since I send to those unfortunate
users regularly without problems. It may be on your ISPs end, but definitely
not an OE concern.

Maybe they don't like the Yale and Harvard mix? eg

Hi CWLee,

Technically, the local mailbox part of the address is case sensitive, but
this is rarely enforced so that e-mail moves with fewer problems. It can be,
however.

The domain part of the address is not case sensitive.

The address you see, and which is in the From line of the email,
may NOT be the address used if you press Reply. E-mail headers
contain a "Return Path" which is the address the email will
actually go to. Actually, this can be done with OE also, if you
look in Accounts, Options, I forget which tab. There is a "reply
to" in addition to your email address there.
So, the aol address may not even exist, although you -think-
that's where you're replying to.
With OE, if you put the cursor in the email body and then press
CTRL-F3, you can look at all the headers; look for Return Path to
see where the mail actually goes. I don't know about other mail
readers; I do know AOL makes it difficult to see the headers if
you're on AOL.

HTH,
Pop

Scan down to this section:

2.4 General Syntax Principles and Transaction Model

You will see that the "local-part" of an e-mail address, that is, the
part to the left of the '@' symbol, is _supposed_ to be treated as
case-sensitive; thus, and
are _supposed_ to be two different entities.

Assuming I interpreted that section properly...

Alas, that has nothing to do with the issue of case sensitivity in the
"local-part" of the e-mail address. That _was_ the OP's problem.

The Internet standards allow the part before the @ to be case sensitive
(the part after the @ never is case sensitive).

However, very few ISPs use case sensitive e-mail addresses. As far as
I know, AOL is not case sensitive. I don't think any of the major ISPs
are.

Take a look at the Message Source (Ctrl-F3) for one of the messages from
your friend. Look for a "Reply To" header. If present, that's what is
used for replies. If not present, look at the "From:" header.

You may find what you friend sent as his new e-mail address is wrong.
