according to RFC822
SYNOPSIS
use Mail::RFC822::Address qw(valid validlist);
if (valid("pdw@ex-parrot.com")) {
print "That's a valid address\n";
}
if (validlist("pdw@ex-parrot.com, other@elsewhere.com")) {
print "That's a valid list of addresses\n";
}
DESCRIPTIONMail::RFC822::Address validates email addresses against the grammar
described in RFC 822 using regular expressions. How to validate a user
supplied email address is a FAQ (see perlfaq9): the only sure way to
see if a supplied email address is genuine is to send an email to it
and see if the user recieves it. The one useful check that can be
performed on an address is to check that the email address is
syntactically valid. That is what this module does.
This module is functionally equivalent to RFC::RFC822::Address, but
uses regular expressions rather than the Parse::RecDescent parser.
This means that startup time is greatly reduced making it suitable for
use in transient scripts such as CGI scripts.
valid ( address )
Returns true or false to indicate if address is an RFC822 valid
address.
validlist ( addresslist )
In scalar context, returns true if the parameter is an RFC822 valid
list of addresses.
In list context, returns an empty list on failure (an invalid address
was found); otherwise a list whose first element is the number of
addresses found and whose remaining elements are the addresses. This
is needed to disambiguate failure (invalid) from success with no
addresses found, because an empty string is a valid list.
