Question regarding email address
- I recently received an email, i.e. <john@....>
I sent a reply, which was not bounced back. I have not
received an answer, making me wonder if my message is
wandering around lost in cyberspace. Yet when I try to
go to the web site for a look around, my browser reports
an error, "abcdefg.com could not be found. Please
check the name and try again".
Can someone explain how a domain name which does
not exist can be used as an email address? I'm a bit

you're reply would go to.
and/or does your email client otherwise display where the email will go
to "before" you (finally) opt to actually send out this reply.

critical here. Most, if not all of ISP's email servers would not send it out
due to they'd first verify that the domain must exist before they would allow
to send out this email.
There may, however, be some ISP's that do not run this check.
1. But, then (some spammers) have been known to break into a computer and
install a (rogue) email server on. For example,
as a search term at google search engine used to turn up (it's now old news
a rougue email server does what it does/wants, can do so without regard to
check if a domain exists or not.
2. Anyone, spammer or not, can set up their own email server and opt to or not
to check if a domain exists before sending out an email that is "supposedly"
from a certain domain.
When "from" a domain that doesn't exist this could be a faked/forged "from" in
the header of the email. (there is such a thing as faked/forged "from"
Sender Policy Framework (SPF) is something that can police any
forged/faked "from" header. SPF is somewhat in use that I know of but not in
widespread, everywhere useage/implemented.

email addresses does not require a working website. There's different
DNS for accessing a website and for accessing email service. One is
not required by the other, you don't need a valid url to get and send
email and vice versa, you don't need to be able to get and send email
to have a valid url.
Since there was no bounce on the reply, it seems likely that the email
address is valid and the recipient simply hasn't read email or hasn't
chosen to reply.
