Thought on this email validator function

[acey99]

Here's the function:

  function isValidemail($iVal){
   return ( preg_match("/(.*)\@(.*)\.([A-z]{2,8})$/i",$iVal) ) ? 1 : 0;
  }

also is there a way to say "Finger" an address & actually have it work ?

I'm looking to block spam & want email addresses that are valid & actually exist.

what if you have a Euro email address like .co.uk..won't validate

you aslo need to look at header injection attacks where bot co-opt your mail app and use it to send spam

No. The only way to verify that an email is genuine is to get a response back from whoever or whatever reads it. Why do you think so many spam emails have an "unsubscribe option"?
