in thread Email Validation, Round 2

You know that Email::Valid uses this same regex, right? It's a nice piece of Perl, but even the module's own POD says:
Please note that there is no way to determine whether an address is deliverable without attempting delivery (for details, see perlfaq 9).
Of course, as I said in my other comment, validity and deliverability are two different things, and sometimes you only need one.

    If you read the pod a little more carefully, you'll spot this: 
    mxcheck ( <TRUE>|<FALSE> )
   Specifies whether addresses passed to address() should
   be checked for a valid DNS entry.  The default is
   false.

    and this: 
      If an error is encountered, an exception is raised.  This
  is really only possible when performing DNS queries.  Trap
  any exceptions by wrapping the call in an eval block:

  eval {
       $addr = Email::Valid->address( -address => 'maurice@hevanet.com
+',
                                     -mxcheck => 1 );
       };
       warn "an error was encountered: $@" if $@;

    I said that Email::Valid will "verify that the target domain exists", not that the email address is ultimately deliverable.

      this is what i include in anything
      that needs email validation
      hope its of use
      notice the use of mxcheck!
      use Email::Valid;

   
sub emailvalidate {
my $evalid= Email::Valid->address( -address =>$_[0],-mxcheck => 1) ? '
+yes' : 'no';
return  $evalid;
}

      I agree, and I did read the POD carefully. My point was orthogonal to yours, not in opposition to it. (My unstated point was that verifiying the target domain, while a nice and clever feature, is not likely to be very helpful. With all the "typo-squatting" these days, it won't even catch most typos.)

      My last sentence was just an acknowledgement that people use Email::Valid for different purposes, and not all of these purposes necessitate deliverability checking.
