=head1 SYNOPSIS |
130
|
|
|
|
|
|
|
|
131
|
|
|
|
|
|
|
String::Validator::Email is part of the String Validator Collection. It will |
132
|
|
|
|
|
|
|
check a string against any number of email validation rules, and optionally |
133
|
|
|
|
|
|
|
against a second string (as in a confirmation box on a webform). |

=head1 String::Validator Methods and Usage |
136
|
|
|
|
|
|
|
|
137
|
|
|
|
|
|
|
Provides and conforms to all of the standard String::Validator methods, |
138
|
|
|
|
|
|
|
please see String::Validator for general documentation, and |
139
|
|
|
|
|
|
|
String::Validator::Common for information on the base String::Validator Class. |

=head1 Methods Specific to String::Validator::Email |
142
|
|
|
|
|
|
|
|
143
|
|
|
|
|
|
|
=head2 Parameters to New with (default) behaviour. |
144
|
|
|
|
|
|
|
|
145
|
|
|
|
|
|
|
mxcheck (OFF) : Perform MX Lookup for Domain Given. |
146
|
|
|
|
|
|
|
tldcheck (ON ) : Validate TLD against a List. |
147
|
|
|
|
|
|
|
fqdn (ON ) : Require a Fully Qualified Domain Name. |
148
|
|
|
|
|
|
|
allow_ip (OFF) : Allow @[ip] (forces tld & fqdn off.) |
149
|
|
|
|
|
|
|
min_len (OFF) |
150
|
|
|
|
|
|
|
max_len (OFF) |
151
|
|
|
|
|
|
|
|
152
|
|
|
|
|
|
|
Important notes -- SVE uses Email::Valid, however, tldcheck is defaulted to on. |
153
|
|
|
|
|
|
|
The choice to turn tldcheck should be obvious. The fudge and local_rules |
154
|
|
|
|
|
|
|
options are specific to aol and compuserve, and are not supported. |
155
|
|
|
|
|
|
|
Finally mxcheck is not tried if there is already an error, since Email::Valid's |
156
|
|
|
|
|
|
|
DNS check does not work, that is performed directly through Net::DNS. |

159
|
|
|
|
|
|
|
|
160
|
|
|
|
|
|
|
Email::Valid provides very terse errors, Expound provides errors more appropriate |
161
|
|
|
|
|
|
|
for returning to an end user. |

=head1 Example |
164
|
|
|
|
|
|
|
|
165
|
|
|
|
|
|
|
use String::Validator::Email ; |
166
|
|
|
|
|
|
|
my $Validator = String::Validator::Email->new() ; |
167
|
|
|
|
|
|
|
if ( $Validator->Is_Valid( 'real@address.com' ) { say "good" } |
168
|
|
|
|
|
|
|
if ( $Validator->IsNot_Valid( 'bad@address=com') { say $Validator->Errstr() } |

=head1 ToDo |
171
|
|
|
|
|
|
|
|
172
|
|
|
|
|
|
|
The major TO DO items are to replace Email::Valid methods, return an Email::Address object and to use it to create methods for returning information |
173
|
|
|
|
|
|
|
from an extended mail string like: Jane Brown . |
