I recently discovered that Google mail accounts (gmail) allows a unique
form of e-mail address. It turns out you can use your e-mail name and
add a plus sign (+) and some other word to form a valid e-mail address.
For example, if I had an account at gmail with my user name of
not-my-real-address, I could do something like this:
[EMAIL PROTECTED]
and mail would be delivered to not-my-real-address, but the To: address
would show as [EMAIL PROTECTED]
'+' is allowed in RFC822 addresses. It has been allowed in email
addresses as far back as I can remember on ARPAnet (1988).
IIRC, CMU was the first to use "+" to allow local aliases on Andrew
(their own OS/FS combination). Individual users could give out a
"[EMAIL PROTECTED]" address and the email would get
delivered to user "basename" into an mbox file "alias".
I have done some tests and this works great. I can now create arbitrary
e-mail address for various accounts and know where it came from or who
leaked my e-mail address.
Ayup, that's what I use it for. I generally combine it with something
like "[EMAIL PROTECTED]". That way I can
eventually set up the mail server to reject all email to disposable1
once it becomes overrun with spam.
I'm I wrong, or are these web sites that do e-mail address validation
screwed up?
It's the websites. I had this problem recently with VMWare.
