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
