NAME

6       Mail::RFC822::Address - Perl extension for validating email addresses
7       according to RFC822
8

SYNOPSIS

10         use Mail::RFC822::Address qw(valid validlist);
11
12         if (valid("pdw@ex-parrot.com")) {
13             print "That's a valid address\n";
14         }
15
16         if (validlist("pdw@ex-parrot.com, other@elsewhere.com")) {
17             print "That's a valid list of addresses\n";
18         }

DESCRIPTION

21       Mail::RFC822::Address validates email addresses against the grammar
22       described in RFC 822 using regular expressions.  How to validate a user
23       supplied email address is a FAQ (see perlfaq9): the only sure way to
24       see if a supplied email address is genuine is to send an email to it
25       and see if the user recieves it.  The one useful check that can be
26       performed on an address is to check that the email address is
27       syntactically valid.  That is what this module does.
28
29       This module is functionally equivalent to RFC::RFC822::Address, but
30       uses regular expressions rather than the Parse::RecDescent parser.
31       This means that startup time is greatly reduced making it suitable for
32       use in transient scripts such as CGI scripts.
33
34   valid ( address )
35       Returns true or false to indicate if address is an RFC822 valid
36       address.
37
38   validlist ( addresslist )
39       In scalar context, returns true if the parameter is an RFC822 valid
40       list of addresses.
41
42       In list context, returns an empty list on failure (an invalid address
43       was found); otherwise a list whose first element is the number of
44       addresses found and whose remaining elements are the addresses.  This
45       is needed to disambiguate failure (invalid) from success with no
46       addresses found, because an empty string is a valid list.
