Hello I have been using this code for a long time to check email addresses to see if they are valid. Now all of a sudden I get a call from someone with a valid email address that gets my 'invalid email address' message. His domain is in this format: firstnamelastinitial@swat.coop
swat.coop is the real domain name.

Here is my code: 
if ($f->{name} eq "email" && ($value =~ /(@.*@)|(\.\.)|(@\.)|(\.@)|(^\
+.) / || $value !~ /^.+\@(\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,3}|[0-9]{1
+,3})(\]?)$/)) {
    $f->{errors} = "Invalid Email Address!";
    $errors++;
}

So my question is do you know of a better more efficient way to validate an email address?

What I mean is that there are so many different modules out there which one is best, this code worked, so I thought, I have used it for a very long time and did not even realize that domains with greater than 3 character .TLD's would not work...

thx,
Richard
