SYNOPSIS

Example usage:

    use Email::IsEmail qw/IsEmail/;

    my $valid = Email::IsEmail('test@example.org');
    ...
    my $checkDNS    = 0;   # do not check DNS (default)
    my $error_level = -1;  # use dafault error threshold: Email::IsEmail::THRESHOLD
    my %parse_data  = ();  # collect E-mail components

    $valid = IsEmail( 'test@[127.0.0.1]', $checkDNS, $error_level, \%parse_data );

    print "Local-part: ",     $parse_data{Email::IsEmail::COMPONENT_LOCALPART}, "\n";
    print "Domain: ",         $parse_data{Email::IsEmail::COMPONENT_DOMAIN}, "\n";
    # only for IPv4/IPv6 addresses:
    print "Domain literal: ", $parse_data{Email::IsEmail::COMPONENT_LITERAL}, "\n";

FUNCTIONS

IsEmail
  my $valid = Email::IsEmail( $email, $checkDNS, $errorlevel, $parsedata );

Check that an email address conforms to RFCs 5321, 5322 and others

As of Version 3.0, we are now distinguishing clearly between a Mailbox as defined by RFC 5321 and an addr-spec as defined by RFC 5322. Depending on the context, either can be regarded as a valid email address. The RFC 5321 Mailbox specification is more restrictive (comments, white space and obsolete forms are not allowed)

    @param string   $email          The email address to check
    @param boolean  $checkDNS       If true then a DNS check for MX records will be made
    @param int      $errorlevel     Determines the boundary between valid and invalid addresses.
                                    Status codes above this number will be returned as-is,
                                    status codes below will be returned as Email::IsEmail::VALID. Thus the
                                    calling program can simply look for Email::IsEmail::VALID if it is
                                    only interested in whether an address is valid or not. The
                                    errorlevel will determine how "picky" Email::IsEmail() is about
                                    the address.

                                    If omitted or passed as -1 then Email::IsEmail() will return
                                    true or false rather than an integer error or warning.

                                    NB Note the difference between $errorlevel = -1 and
                                    $errorlevel = 0
    @param hashref  $parsedata      If passed, returns the parsed address components
