AAAAHHHH!!! email addresses are a programmer's nightmare

[thehacker]

from RFC 2486 ...

a valid Network Address Identifier (email address) is:

username = dot-string

realm = realm "." label

label = let-dig * (ldh-str)

ldh-str = *( Alpha / Digit / "-" ) let-dig

dot-string = string / ( dot-string "." string )

string = char / ( string char )

char = c / ( "\" x )

let-dig = Alpha / Digit

Alpha = %x41-5A / %x61-7A ; A-Z / a-z

Digit = %x30-39 ;0-9

c = < any one of the 128 ASCII characters, but not any special or SP

x = %x00-7F

; all 127 ASCII characters, no exception

SP = %x20

; Space character

special = "<" / ">" / "(" / ")" / "[" / "]" / "\" / "."

/ "," / ";" / ":" / "@" / %x22 / Ctl

Ctl = %x00-1F / %x7F

; the control characters

; (ASCII codes 0 through 31 inclusive and 127)

if you are using perl, you can try this regular expression:

(taken from rootworks.com/rx - where i learned regexp 5 years ago)

if ($c =~ /^([a-zA-Z\-_]+)@(([a-zA-Z\-_]+)\.)+([a-zA-Z]+)$/)

{

print "YES! - probably an email address\n";

print "user was $1\n";

print "domain was $2\n";

print "TLD was $3\n";

}

else

{

print "definitely NOT an email address, loser\n";

}

this works in php

if ((!$email) || ($email=="") || (!eregi("^[_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3}$",$email))) {

echo "Put in a valid email... stoooopid"

}

[thehacker]

well, here's my hack in coldfusion:

<cfif NOT refindnocase("^(([0-9A-Za-z_\-]+\.)*)(([0-9A-Za-z_\-])+)(@)(([0-9A-Za-z_\-]+\.)+)([0-9A-Za-z_\-]{2,})$",attributes.email)>

<cfset valid = 0>

<cfset user_error = listappend(user_error,"Email address is not properly formatted.","|")>

</cfif>

basically it'll accept things like:

are.you.receiving.me@domain.co.uk

me@domain.com

you@minnesota.museum [yes it is a TLD - i was surprised too!]

hi_there-mr.crazy@person.com

obviously it would be nice to accept the IP-address variant too.

is it:

blah@[0.0.0.0]

or...

bleck@0.0.0.0

?

why coldfusion? because i'm a sadomasochist.

and it also happens to be my workplace standard. mer.
