Summary: filter_var($e, FILTER_VALIDATE_EMAIL) won't validate
spaces in quoted strings

New Comment:
It seems that the function and filter work perfectly in all cases.
It was my misunderstanding of the regulations that was at fault. I have edited
Wikipedia to show what is correct (never read so many regulations in my life!)
and
hope you'll forgive my rush to accuse. My intentions were to help not hinder.
Yours, Fred Gandt.

I reread and read some extra, edited and re-edited Wikipedia and now have to
suggest reopening this bug report. It seems I was right in the first place:
Quoted strings containing spaces should validate (return true).
See: http://tools.ietf.org/html/rfc3696#section-3 for confirmation.
\ \ \ \ @example.com FALSE incorrect since spaces can exist as slashed doublets
"abc def"@example.com FALSE incorrect
abc"123@456"[email protected] FALSE cannot find regulation stating that it
should
be invalid.
abc"123 456"[email protected] FLASE also should be valid (it seems)
abc"123"[email protected] FALSE also, so not a space issue but that the quotes
are
not outermost of the local-part
[email protected] TRUE incorrect
\\\\\\\\@example.com FALSE incorrect since backslash can quote itself this
should be accepted
I think there are a few problems need addressing (pun intended).

Really sorry. RFC is hard to read so I relied on Wikipedia (usually very good
with
this kind of thing). Spaces aren't ever allowed. Not even within quotes. Going
to
edit Wikipedia now instead of waste your time.
Forgive? ;-)

IMPORTANT: I am a learner. Sorry if I am wasting your time. Also GoDaddy don't
supply much in the way of detail about what version is running. All I know is
that it is 5.3.? I have asked for the rest but am still waiting.
Using filter_var($e, FILTER_VALIDATE_EMAIL) where $e is a submitted email
address that according to RFC 5321 and Wikipedias clearer to understand
interpretation of it should be considered valid, the return can be invalid
where
spaces are featured within quoted strings.
e.g.
A-Za-z0-9."?Oooh![what]{fun}|is|!".gladthisisn'tmyaddress@[32.64.128.1] ==
valid
(impressive)
"Fred Gandt"@fredgandt.com == invalid
Take the space out and "FredGandt"@fredgandt.com == valid
I've tested all the most unusual combinations I can think of and
FILTER_VALIDATE_EMAIL seems to only fail with spaces being disallowed outright
rather than only being disallowed when not enclosed by quotes (as with other
otherwise disallowed chars).
If my interpretation of RFC 5321 is wrong and spaces are in fact never allowed
(even when enclosed by quotes) please forgive my impertinence.
Love PHP. Very slick and user friendlyness abounds!
Test script:
---------------
<html><body><br>
<form action="" method="post">
<input type="text" name="email" size="100">
<input type="submit" value="POST"><br><br>
<?php
$e=$_REQUEST["email"];
$result=filter_var($e, FILTER_VALIDATE_EMAIL);
if($result){echo($e."<br><br><b style=\"color:#008800;\">Valid Email
Address</b>");}
else{echo($e."<br><br><b style=\"color:#ff0000;\">Invalid Email Address</b>");}
?>
</form></body></html>
Expected result:
----------------
Test script provides form entry field "input type="text""
Fill in "textbox" with email address having a local-part with a quoted string
containing spaces.
e.g. "Fred Gandt"@fredgandt.com
Submit
EXPECT: Return (echo) == Valid
Actual result:
--------------
OBSERVE: Return (echo) == Invalid
