Verify if an email address exists.

[Dan Dubovik]

Sort of depends on what you are looking for.  There are some domains that
have a catch all, so may not go to the specific address you mail to.

What are you wanting to accomplish with this?  If you want to know if you
can send mail to a specific domain, you can open a socket to the domain on
port 25 (assuming you have outbound port 25 available to you from your
location).

If you want to know if a specific email address is available, you can try to
send an email to the address, and note the response code after sending it.
Using php, you can use the mail() function, however, the error message it
returns is binary in nature, either it sends or not, without a real reason
why it failed to send.
