looking for a good/working/tested php email validation regex that conforms

a lot of what i've seen from google breaks, or doesn't follow the standard!
any ideas/thoughts/sample code/etc...
I use this code to build the regex
$tld='[a-z]{2,}';
$regexp='^([_a-z0-9-]+)(\.[_a-z0-9-]+)*'.
'@([a-z0-9-]+)(\.[a-z0-9-]+)*(\.'.$tld.')$';
And test it like this:
/* BEGIN PHP code*/
if (eregi($regexp, $email))
{
list($username,$domaintld) = split("@",$email);
// Validate domain
if (getmxrr($domaintld,$mxrecords)) {
$valid = true;
/*print("Domain: $domaintld");
foreach($mxrecords as $mxKey => $mxValue)
print(" $mxValue");*/
} else {
if (checkdnsrr($domaintld, "any"))
$valid=true;
else
$errors.="The domain ('$domaintld') is
invalid.".
" Please check the email.";
}
} else {
$errors.="The email ('$email') isn't valid.";
$valid = false;
}
/* END PHP code*/
I used to get TLD list from
http://data.iana.org/TLD/tlds-alpha-by-domain.txt
Replacing the above TLD with
/*$tld =
'(AC|AD|AE|AERO|AF|AG|AI|AL|AM|AN|AO|AQ|AR|ARPA|AS|AT|AU|AW|AZ|'.
'BA|BB|BD|BE|BF|BG|BH|BI|BIZ|BJ|BM|BN|BO|BR|BS|BT|BV|BW|BY|BZ|CA|CC|'. 'CD|CF|CG|CH|CI|CK|CL|CM|CN|CO|COM|COOP|CR|CU|CV|CX|CY|CZ|DE|DJ|DK|DM'.
'|DO|DZ|EC|EDU|EE|EG|ER|ES|ET|EU|FI|FJ|FK|FM|FO|FR|GA|GB|GD|GE|GF|GG|GH|'.
'GI|GL|GM|GN|GOV|GP|GQ|GR|GS|GT|GU|GW|GY|HK|HM|HN|HR|HT|HU|ID|IE|IL|'. 'IM|IN|INFO|INT|IO|IQ|IR|IS|IT|JE|JM|JO|JP|KE|KG|KH|KI|KM|KN|KR|KW|KY'.
'|KZ|LA|LB|LC|LI|LK|LR|LS|LT|LU|LV|LY|MA|MC|MD|MG|MH|MIL|MK|ML|MM|MN|'. 'MO|MP|MQ|MR|MS|MT|MU|MUSEUM|MV|MW|MX|MY|MZ|NA|NAME|NC|NE|NET|NF|NG|'.
'NI|NL|NO|NP|NR|NU|NZ|OM|ORG|PA|PE|PF|PG|PH|PK|PL|PM|PN|PR|PRO|PS|PT|'. 'PW|PY|QA|RE|RO|RU|RW|SA|SB|SC|SD|SE|SG|SH|SI|SJ|SK|SL|SM|SN|SO|SR|ST'.
'|SU|SV|SY|SZ|TC|TD|TF|TG|TH|TJ|TK|TL|TM|TN|TO|TP|TR|TT|TV|TW|TZ|UA|'.
'UG|UK|UM|US|UY|UZ|VA|VC|VE|VG|VI|VN|VU|WF|WS|YE|YT|YU|ZA|ZM|ZW)';
*/
But as I check if the email domain part is exists, this is not needed.
This is fairly good, and is adapted from a page that i don't have here
the reference. I think that it is RFC compatible in the regex, cause I
remember to see it to build the regex. The domain check code is adapted
as the in the original code it only checks for MX records, but in the
RFC says that if no MX records exist (where he should deliver), try to
deliver to the machine, e.g., if no mail.isp.com MX records exist, try
to deliver the message to the mail.isp.com machine (with SMTP, obviously).
PS: your Perl solution can be good, but I think that there exist PHP
classes that do it, but I don't know one.

RE: [PHP] email validation regex
perl has a mod "email::valid" that claims to do email validation, and it
appears to be fairly complex/lengthy.
i'm considering simply using this in a perl app, that i'd then call from the
php function...
use the best tool for the job in the quickest manner!!!

This will be fun, everybody has their own which is always best. No two
people
will agree what is correct method and will always come with a 'better' one.
This is generally accompanied by derision and ridicule of the others.
To this end, I will start the ball rolling with this one...
preg_match('/[EMAIL PROTECTED],}\.[\w]{2,6}$/iU', $email)
